SUS630, as a martensitic precipitation-hardening stainless steel, is widely known by a common international name 17-4PH. Under different standards worldwide, it also has specific corresponding designations, as detailed below: Japan: The corresponding des...

When selecting cutting tools for machining SUS630 (martensitic precipitation-hardening stainless steel), its heat treatment condition (lower hardness in the solution-treated state and higher hardness in the aged state) must be considered. Tool selection s...

SUS630 is a martensitic precipitation-hardening stainless steel under the Japanese JIS standard, corresponding to the American grade 17-4PH and the Chinese grade 05Cr17Ni4Cu4Nb. Its core advantage lies in the ability to precisely control strength and hard...

SUS630 is magnetic, and the strength of its magnetism varies with heat treatment. Magnetism in different states: Solution-treated state: Weak magnetism. The microstructure is primarily austenitic with a small amount of martensite, showing only slight ma...

The hardness of SUS630 is directly related to its heat treatment state, ranging from 28–32 HRB (solution-treated) to 30–45 HRC (aged), with lower aging temperatures producing higher hardness. Hardness in different states: Solution-treated: H...

SUS630 is a martensitic precipitation-hardening stainless steel under the Japanese JIS standard, corresponding to 17-4PH (US) and 05Cr17Ni4Cu4Nb (China). It offers a balance of high strength and moderate corrosion resistance through heat treatment. Core ...

SUS630 (martensitic precipitation-hardening stainless steel) uses a two-step heat treatment process: solution treatment + aging treatment. This process adjusts strength and hardness, and post-weld parts require re-aging to restore performance. Detailed st...

The hardness of SUS630 is determined by both solution treatment and aging treatment. Aging temperature plays a key role, and hardness varies significantly with different heat treatment states. 1. Hardness after Solution Treatment After solution treatmen...

SUS630 exhibits distinct performance gradients after solution and different-temperature aging treatments. Heat treatment also affects corrosion resistance, magnetism, and other properties. 1. Performance after solution treatment * Temperature range: 102...

The core process for SUS630 (17-4PH) revolves around machining and heat treatment, with the main goal of achieving high strength through “solution + aging” treatment. Machining parameters need to match the material’s condition. 1. Heat ...

SUS630 (martensitic precipitation-hardening stainless steel) and 304 (austenitic stainless steel) differ mainly in material type, performance focus, and application scenarios. SUS630 emphasizes high strength, while 304 emphasizes corrosion resistance and ...

SUS630 (martensitic precipitation-hardening stainless steel) and 201 (austenitic stainless steel) differ significantly in material type, properties, and application scenarios. SUS630 focuses on high strength, while 201 emphasizes low cost and basic corros...
