Product Description

ASTM A240/A240m SUS630 0Cr17Ni4Cu4Nb Heat Resistance at Higher Temperatures Corrosion Resistance Seamless Stainless Steel Pipe

630 stainless steel is a highly representative chromium molybdenum alloy stainless steel material, which has improved chemical composition, processing performance, corrosion resistance, and other properties using ordinary carbon steel. 630 stainless steel is mainly used in GB/T 1220-2007 stainless steel bar technical requirements related standards, mainly in accordance with American ASTM standards (A564, A693, A705, A965, A1016, etc.), European standards (EN 10088-3, EN 10250-4, EN 10272, etc.), and Japanese standards.

2, 630 stainless steel performance

1. Corrosion resistance: 630 stainless steel is a type of stainless steel with high hardness and good corrosion resistance. It is a type of steel that is resistant to high temperature, acid, and wear. 630 stainless steel has good heat resistance at higher temperatures and good corrosion resistance in neutral or slightly acidic alkaline environments.

2. Mechanical properties: 630 stainless steel is a high-strength stainless steel with very high strength and hardness. In high-temperature environments, the hardness and strength of 630 stainless steel remain good. Appropriate steel heat treatment can improve the mechanical properties of 630 stainless steel, increasing its strength to over 300MPa.

3. Processing performance: 630 stainless steel not only has good corrosion resistance, but also has good processing performance. Steel has a high hardness, but due to the chemical composition and high hardness of stainless steel, the precision of machining dimensions can be controlled through precise machining techniques to meet the manufacturing needs of precision components.

4. Thermal stability: 630 stainless steel has good thermal stability and can resist mechanical wear and other thermal and chemical effects that can degrade its performance.

In summary, 630 stainless steel is a high-quality stainless steel material widely used in modern industry. It has excellent properties such as corrosion resistance, high temperature resistance, high strength, high hardness, excellent processing performance, and thermal stability, and is widely used in high-strength and heavy-duty engineering fields such as manufacturing chemicals, aviation and aerospace, marine structures, and automotive parts.
