Steel standards are systems for classifying, evaluating and specifying the chemical, mechanical and metallurgical properties of different types of steels and ferrous alloys that are used in the production of components, machinery and constructions. Steels are classified by a large variety of criteria such as:
Composition e.g. carbon, low-alloy, or stainless steel; method of manufacturing such as open hearth, basic oxygen process, or electric arc furnace methods; finishing method such as hot rolling, cold rolling and various surface finishing and plating techniques; product form e.g. bar, wire, plate, sheet, strip, tubing or structural shape; deoxidation practice such as killed, semi-killed, capped or rimmed steel; microstructure such as ferritic, pearlitic and martensitic and heat treatment such as annealing, quenching and tempering.
There are a number of classification and designation systems accepted and used worldwide, which are developed and standardised either nationally and internationally by Standard Development Organisations (SDOs) or by specific vertical industries or suppliers.
Some of the more frequently used steel standard and classification systems include:
AISI (American Iron and Steel Institute) steel standards, which are traditionally used in the US and abroad.
EN (Euronorm), which is a harmonised system of metal and steel standards of European countries. Although it is accepted and effectively used in all European countries, “obsolete” national systems, such as German DIN, British BS, French AFNOR and Italian UNI are commonly used and often found in many documents and specifications.
Japanese JIS steel standards, which are widely used in Asia and Pacific regions. JIS steel specifications have also often been used as a base for other national systems such as Korean, Chinese, and Taiwanese standards. Steel standards of newly industrial countries such as Chinese GB and YB, Indian IS and Brazilian NBR, although sometimes less developed and detailed, are increasingly being used due to global sourcing. The same applies for Russian GOST, which is practically the de facto standard for the whole Community of Independent States.
Symbols used in European Standards e.g. hot rolled products of structural steel BS EN 10025:2004:
- S… Structural Steel
- E… Engineering Steel
- H… Hollow Steel
- …JR.. Longitudinal Charpy V-notch impacts 27 J at +20°C
- …JO.. Longitudinal Charpy V-notch impacts 27 J at 0°C
- …J2.. Longitudinal Charpy V-notch impacts 27 J at -20°C
- …K2.. Longitudinal Charpy V-notch impacts 40 J at -20°C
- .235… Minimum yield strength (Reh) in MPa at 16mm
- .275… Minimum yield strength (Reh) in MPa at 16mm
- .355… Minimum yield strength (Reh) in MPa at 16mm
Test certification is not mandatory in BS EN 10025 and must be specified when ordering from Tomrods.

Tomrods Ltd operates as a general steel trading business with the added service of offering a large range of stocks for sale and delivery within 24 hours from the time of order receipt.
As we are not directly involved in the manufacture of the steel, the environmental impact of our activity is minimal. However, we are acutely aware of the processes involved in steel making and therefore have a strong policy to mitigate any supply chain environmental impact.
It is the Company’s policy to supply and deliver its products in a manner that minimises the impact on the environment where practicable.
The Company considers that matters regarding the environment are an objective to be shared by all employees, suppliers and customers of the Company and it regards environmental issues as being of equal value to Quality, Health and Safety, or any other business objective.
It is the Company’s policy to implement systems for continuous improvement in all fields of operation and these will be integrated into all management functions.
Tomrods Ltd recognises that to have a planned approach to the prevention and reduction of waste and pollution leads to a long term reduction of costs.
Tomrods Ltd will control its activities to avoid unnecessary and unacceptable risks or adverse effects on the environment, in line with the requirements of the Health & Safety at Work Act 1974 and the Environmental Protection Act 1990.
Environmental awareness and individual responsibility will be developed amongst employees at all levels and effective consultation will be encouraged. The Company will develop and improve standards by making use of available technology and developments, together with waste recovery and a recycle approach. Plant, vehicles and equipment will be maintained and operated to provide maximum environmental protection as far as is practical.
Clients, employees and the general public who may be affected will be made aware of any Company activity that may affect the environment.
Management will take individual responsibility to ensure that environmental issues are considered when making decisions and when planning or controlling works. This includes the minimisation of transport usage by having materials delivered from the nearest producer to our sites.
All employees must recognise their individual responsibilities for carrying out their works in a sympathetic manner with respect to the environment.
All employees must give careful consideration to the elimination and reduction of waste.
Where recycling or re-use of a material is an economical advantage this will be considered.
Health & Safety Policy
Tomrods Ltd is committed to pursuing excellence in everything it does and this includes the management of health & safety.
Tomrods Ltd will take all reasonably practicable precautions to ensure the Health & Safety at work of its employees whether at the Company premises or when carrying out its business elsewhere and also recognises that a duty of care extends to other persons whilst they are on Company premises.
The responsibility for safety at work belongs to all Company employees be they upper management, junior management or operatives and to employees of contractors variously employed. The Company through its employees also accepts responsibility for the Health & Safety of others affected by its actions.
To achieve these aims the Company will:
- Provide a safe working environment in the operation and maintenance of all equipment, and facilities.
- Establish safe systems of work.

By minimising pollution and waste; improving health and safety; and increasing our competitive edge; Tomrods Ltd has also established itself as a standard bearer for sustainability in our field.
Steel Grades Explained
Steel Grades Explained
Mild steel is the most common form of steel because its price is relatively low whilst it provides material properties that are acceptable for many applications. This steel usually contains less than 0.25% of carbon and insignificant amounts of alloying elements.
The material exhibits good weldability properties and is used in most general fabrication and structural steel applications.
In general we talk of two types of mild steel – bright and black:
- Bright mild steel as its name suggests is shiny to look at with a clean and slightly oiled finish.
- Black mild steel has a rougher, scaled finish that is dry to the touch.
High Yield Steels
High yield steel is another low carbon steel also typically containing less than 0.25% of carbon but the steel strength is increased through the addition of manganese and/or vanadium. This type of steel can also be further enhanced through small additions of molybdenum, niobium and titanium. This material again exhibits good weldability properties and is used in more demanding structural applications.
Carbon steels which can successfully undergo heat-treatment have a carbon content in the range of 0.30-1.70%. This type of steel is generally very strong with high levels of wear resistance. The steel is often used for hot forging/pressing components such as hand tools. Material in the higher band of carbon is also used for making high strength wires for applications such as spring steel.
Boron steel is a grade of steel, which can be processed at high temperatures by heating it in a furnace and pressing whilst still hot, using a cooled tool. The rapid cooling rate transforms the microstructure to form a very hard, tough and durable steel. This type of steel is used to form wear parts and for other applications where exceptional strength and wearability properties are required.
Engineering steels, also known as Special Bar Quality steels, represents a wide variety of higher-quality carbon alloy and free cutting bars that are used in the forging, machining and cold-drawing industries for the production of automotive parts, hand tools, electric motor shafts and valves. These steels generally contain higher alloy content than the commodity grades and are produced with more precise dimensions and chemistry.
