GB standards for steel materials

Sommario:

This group of Chinese (GB) standard specifications covers carbon and alloy steel plates and forgings used in boilers and pressure vessels, high-strength low-alloy steels, heat-treatable steels, hot and cold-rolled plates for cold forming, steels for concrete reinforcement and prestressed concrete and the properties for railway service rails and accessories. Standards for various types of steel pipe which specify requirements for high-temperature service, ordinary use, and special applications such as fire protection use, are also presented. Specifications for steel tubes list standard requirements for boiler and superheater tubes, general service tubes, still tubes in refinery service, heat exchanger and condenser tubes, mechanical and structural tubing. Steel casting specifications call out the standard properties for pressure purposes.

Review of GB Standards for steel consists of one volume. It contains formally approved GB standard classifications, guides, practices, specifications, test methods and terminology and related material such as proposals.

Covers:

The following data are given for each standard: standard number, grade, chemical composition and mechanical properties (yield point, tensile strength, notch toughness). When deemed useful, steel type, manufacturing method, thickness of plate, heat treatment and other data are described.
