Product Description
630 stainless steel plate stainless steel coil 1500*6000 machinery manufacturing plate.
630 stainless steel is a martensitic precipitation hardening stainless steel with adjustable strength levels through heat treatment processes. Its main strengthening mechanisms are martensitic phase transformation and aging treatment to form precipitation hardening phases.
This grade offers excellent attenuation performance, strong corrosion fatigue resistance, and water drop resistance.

Key Properties
630 stainless steel is a precipitation hardening, martensitic stainless steel composed of copper and niobium/columbium, offering:
- High strength and hardness (up to 300°C/572°F)
- Excellent corrosion resistance comparable to 304 and 430 grades
- Compressive strengths up to 1100-1300 MPa (160-190 ksi) after heat treatment
- Good resistance to atmospheric conditions and dilute acids/salts
- High elongation and work hardening rate
- Excellent low-temperature performance down to -196°C
Note: Not recommended for use above 300°C (572°F) or at very low temperatures.
Applications
- Offshore platforms, helicopter decks, and other marine structures
- Food processing equipment
- Pulp and paper industry machinery
- Aerospace components (turbine blades)
- High-performance mechanical components
- Nuclear waste containment drums
- Deep well pipes and bolts
