Division 1 In this chapter, the following expressions have the meanings hereby assigned to them:

Alloy pig iron

Pig iron containing, by weight, one or more of the following elements in the specified proportions:

• more than 0,2 % of chromium,

• more than 0,3 % of copper,

• more than 0,3 % of nickel,

• more than 0,1 % of any of the following elements: aluminium, molybdenum, titanium, tungsten (wolfram), vanadium.

Non-alloy free-cutting steel

Non-alloy steel containing, by weight, one or more of the following elements in the specified proportions:

• 0,08 % or more of sulphur,

• 0,1 % or more of lead,

• more than 0,05 % of selenium,

• more than 0,01 % of tellurium,

• more than 0,05 % of bismuth.

Silicon-electrical steel

Alloy steels containing by weight at least 0,6 % but not more than 6 % of silicon and not more than 0,08 % of carbon. They may also contain by weight not more than 1 % of aluminium but no other element in a proportion that would give the steel the characteristics of another alloy steel.

High-speed steel

Alloy steels containing, with or without other elements, at least two of the three elements molybdenum, tungsten and vanadium with a combined content by weight of 7 % or more, 0,6 % or more of carbon and 3 to 6 % of chromium.

Silico-manganese steel

Alloy steels containing by weight:

• not more than 0,7 % of carbon,

• 0,5 % or more but not more than 1,9 % of manganese, and

• 0,6 % or more but not more than 2,3 % of silicon, but no other element in a proportion that would give the steel the characteristics of another alloy steel.
