Description

This standard specifies requirements for carbon steel and carbon-manganese steel forgings for general engineering purposes with ruling section up to and including 300 mm, and supplied either to chemical composition only, or to chemical composition and mechanical properties in any heat-treated condition, or to chemical composition and mechanical properties in the normalised or normalised and tempered condition.

Scope

The standard provides for the supply of forgings on the following basis:

• (a) Chemical composition only, as specified in Tables 1 to 4.
• (b) Chemical composition as specified in Tables 1 to 4, and hardness or other mechanical properties in any heat-treated condition, as negotiated at the time of enquiry and/or order.
• (c) Chemical composition and mechanical properties in the normalised or normalised and tempered condition as specified in Table 5.

Note: Guidelines to purchasers on requirements that must be specified by the purchaser and those that must be agreed at the time of enquiry and/or order are given in Appendix A.
