Description / Abstract:

Section 1 of this Part of BS 970 specifies the requirements for steelmaking and general testing and inspection procedures for the release of steel in the form of blooms, billets, slabs, bars, rods and forgings, used in the as-rolled, as-forged or softened condition as appropriate and in accordance with the specific requirements for the steels in sections 2 to 5 inclusive. This standard applies to stainless steels only in the form of forgings but to the heat resisting steel 310S31 in both rolled and forged product forms.

NOTE 1 Forgings above 150 mm ruling section in carbon and alloy steels may be ordered in accordance with BS 29 and BS 4670 respectively and released to the requirements of those standards.

NOTE 2 Particular attention is also drawn to the information given in the foreword.

Sections 2 to 6 cover specific requirements for the supply of steels as follows:

— Section 2: As-rolled and as-rolled and softened steels and micro-alloyed carbon manganese steels;

— Section 3: Steels for surface hardening by nitriding;

— Section 4: Case hardening steels;

— Section 5: Stainless and heat resisting steels;

— Section 6: Specifies sizes and tolerances.
