What is 630 Stainless Steel Plate?
The 630 stainless steel plate, also known as 17-4PH, is a precipitation hardening martensitic stainless steel. It contains approximately 17% chromium and 4% nickel, with the addition of copper, niobium, and manganese. The alloy can be heat treated to high strength levels while maintaining good corrosion resistance.
UNS: S17400
Equivalent Grades: ASTM A693 Type 630, DIN 1.4542, X5CrNiCuNb16-4
ASTM A693 Type 630 SS plate
stainless steel sheet Advantages
630 stainless steel plate has a tensile strength of more than 1310MPa (about 2.5 times that of 304 stainless steel) after aging treatment through the copper-niobium precipitation strengthening mechanism, while maintaining an elongation of more than 10%, meeting the stringent load requirements of aerospace fasteners, high-pressure valves, etc. Its fatigue strength can reach 500MPa under 10⁷ cycles, which is suitable for mechanical structures with frequent vibrations.
630 stainless steel corrosion resistant plate has a corrosion resistance close to that of 316L stainless steel in marine or chemical media containing chloride ions, with an annual corrosion rate of <0.02mm. After cold bending, the strength can be increased by 20%, which is suitable for manufacturing complex components such as helicopter decks and pressure vessels.
630 stainless steel cold-rolled plate has a 30%-50% lower cost than nickel-based alloys, while maintaining more than 80% high-temperature strength under working conditions below 600℃, and can reduce weight by 40% by replacing traditional high-strength steel.
Types of 630 SS Plate
In addition, we also provide a variety of surface treatment options such as 2B, 4K, 8K, etc. to meet different needs from industrial applications to decorative purposes.
