Chinese steel grade representation method
China has developed different steel codes and numbers to identify different types of steel. The national standard, the GB/T 222 “Permissible Tolerances for Chemical Composition of Steel Products”, is the basis for the standardization of the various types of steel’s composition in China. Steel gr......
Brief introduction to the representation method of metal material grades in China (GB)
Introduction
China has a unique system of numbering and coding a wide range of metallic materials, called Chinese Standard (GB) Metal Materials Numbering System (in Chinese “gong bu”). Generally, it is a four-digit designations for classifying and determining basic Metal materials.
The Purpose......
Cast tin-based bearing alloy ingot
Introduction
Tin-based bearing alloy dingesare an important part of modern industrial ball bearing and roller bearing components. Compared with other bearing materials, tin-based bearing alloys have superior corrosion resistance, higher temperature fatigue life, good wear resistance and thermal c......
Comparison table of various structural steel grades ranked by minimum tensile strength
Table of Structural Steel Grade Comparison by Tensile Strength
Structural steel grade comparison by tensile strength is an important factor when selecting a structural steel material for a given application. The tensile strength of structural steel materials ranges from 400MPa for mild steels, up......
