What is BS970?

What is BS970?

BS970 steel grades are commonly carbon and alloy steels which can be heat treated to achieve a wide range of tensile strengths and mechanical properties. Some stainless steel specifications are also referenced in BS970.

What is BS970 080M40?

EN8/080M40 steel,as ’40’ carbon steel, is a common unalloyed medium carbon steel as per British standard BS 970.It has medium carbon content with 0.36-0.44% which gives it medium tensile strength.

What is EN9 material?

EN9 is a medium carbon steel grade commonly supplied in the as rolled condition. It can be flame or induction hardened to produce a high surface hardness with excellent wear resistance for a carbon steel grade.

What is fe415 and fe500?

The distinction in the quality between Fe 500 and Fe 415 steel grades is 20%, Fe 500 being 20% stronger than Fe 415. The explanation behind is Fe 415 signifies that power of 415 N/sq.mm is required to deform the TMT bar, whereas Fe-500 denotes that a force of 500 N/sq.mm is required to deform the TMT bar.

What is werkstoff number?

Werkstoff numbers The numeric code is the Werkstoff number, this uses numbers only with a decimal point after the first digit. Werkstoff – material, the stuff something is made from. Below is a table of some of the more popular steel grades we supply along with the BS 970 1991, AISI/SAE and Werkstoff equivalents.

Does EN1A contain lead?

EN1A Leaded (Pb) Steel A low carbon mild steel with added lead. Properties: free cutting, suitable for machining using both automatic and CNC machines. Available in square, round, flat or hexagon form.

Can EN1A be forged?

It has excellent machinability. It is suitable for case hardening and electroplating. We can provide you with free cutting steel both in the black and bright cold drawn bar form….World-wide Grades similar to En1a Steel.

Can you harden EN8?

EN8 or 080m40 can be tempered at a heat of between 550 °C to 660 °C (1022 °F-1220 °F), heating for about 1 hour for every inch of thickness, then cool in oil or water.

Is 709m40t alloy steel BS EN 10204 compliant?

709M40T alloy steel is available with BS EN 10204 3.1 mill certificate, please request when placing any orders. 709M40T is supplied in accordance with our ISO 9001:2015 registration.

What grade is West Yorkshire steel 708m40?

West Yorkshire Steel are suppliers of bright drawn bar and hot rolled black bar. This is a similar grade to 708M40 but with a variation in the molybdenum content and is usually supplied heat treated to ‘T’ condition.

How do you heat treat 709m40?

709M40 is commonly supplied ready heat treated at ‘T’ condition. If further heat treatment is required annealed 709M40 should be heated slowly to 860-890°C and after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature.
