The grade and chemical composition of high speed steel in my country
High-speed steel is a tool material which refers to steels that are able to maintain good hardness and high wear resistance at temperatures up to five times higher than those of the high carbon tool steels. It was invented in 1912 and has seen much development since then. Its main applications inc......

Representation of steel grades in Japan, Britain and France
Introduction
Steel as a material has a variety of grades, forming large classifications that help people differentiate between different types of steel according to their properties. The steel grade system is a hierarchical system of classification designed to separate different steel types based......

Japan Steel Grades
A steel grade is a designation of a particular type of steel. Steel grades are used to distinguish different types of steel based on their unique properties and characteristics. The most popular steel grades in Japan are SS400 and SS490. These two grades are used for general us......
Italian heat-resistant steel grade
Italian heat-resistant steel is a term used to describe several grades of steel which are characterized by their exceptional resistance to high temperature corrosion processes. Heat resistant steel is ideal for the fabrication of components which are exposed to extreme temperatures, such as furnac......
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......
Positive temperature coefficient constant elastic alloy (YB/T5244-1993)
Research paper on zero temperature coefficient springs (YB / T5244-1993)
Abstract
This paper reports on the study of zero temperature coefficient springs (YB / T5244-1993), which are a fairly new type of spring used in temperature-sensitive applications. The mechanism of zero temperature coeffic......
Steel grade and chemical composition (mass fraction) of cast steel for rolls (%)
Chemical Composition(%) and Steel Number of Steel Used for Rolling Rollers
Rolling rollers generally choose high-carbon and low-alloy steels to obtain good dimensional stability and fatigue strength.
1. Steel number 811M40, chemical composition: C 0.36～0.44, Si 0.15～0.35, Mn 0.60～1.00, Cr 0.9......
Corrosion-resistant alloy welding wire GBn 274-88
GBn 274-88 Corrosion-resistant alloy welding wire
Corrosion-resistant alloys provide advantageous properties, such as higher alloy content and higher tensile strength, relative to other alloy welding wires. These properties make them particularly suitable for applications in environments that are......
