Common steels
Four or five large makers worldwide produce most steels available
on the commercial market . These steel producers use the same
techniques and the same chemical content on a large number of
their products. These steels are identical in all but name or
are so similar they can be treated the same. A good example of
this is the Bohler steel K460. This steel has a variety of names
by producer. Its Udderholm equivalent is Arne and its AISI code
O1.]
Other steels such as Ground Flat Stock and Gauge Plate have identical
or very similar alloy content so will require the same heat treatment.

Similar to M2 but higher 'red' hardness
and abrasion resistance. May be vacuum treated. High hardening
temperature leads to risks during heat treatment and increased
chance of distortion. |

| En24 High tensile strength general engineering
steel EN19A Hight tensile and toughness engineering steel
Key to Suppliers: |
High tensile strength make tis steel ideal
for automotive and aircraft components. Higher tensile and
yield strength than En19
Less tensile strength of En24 steel but has a higher toughness
with good hardenability in large section sizes
