Thép không gỉ SUS630

1. Breaking the Reliance on Imports

China has historically depended on imported high-end stainless steel for producing core equipment in high-end medical meltblown cloth production lines. These imports are costly and have long delivery times.

Panchangte’s SUS630 stainless steel, developed domestically, has achieved superior performance in China. It solves issues like cracking caused by high-temperature direct quenching, reducing reliance on imports. The first batch of equipment has already been exported, and additional SUS630 contracts are underway.

2. Characteristics of SUS630 Stainless Steel

SUS630 is a martensitic precipitation-hardening stainless steel, developed from the 18-8CrNi base. It is also called controlled phase change stainless steel.

Đặc điểm chính:

Độ bền và độ cứng cao.
Good welding performance.
Khả năng chống ăn mòn tuyệt vời, better than 4-series stainless steel.
Strong resistance to water drops.
More affordable than 316 thép không gỉ.

Its strength can be adjusted through heat treatment. The main strengthening methods include martensitic phase transformation and aging treatment, forming a precipitation-hardening phase.

Ứng dụng:
SUS630 is widely used in:

The chemical fiber industry.
Valves and shafts.
High-strength parts requiring corrosion resistance.

3. Thành phần hóa học

SUS630 contains less than 0.1% Carbon. Elements like copper, molypden, titan, and aluminum are added. These form carbides and intermetallic compounds, further enhancing the strength of martensitic stainless steel.
