1.4542 AISI 630 Stainless Steel Plate

AISI 630 or 17-4 PH, is a martensitic precipitation-hardening stainless steel that offers an exceptional combination of high strength, corrosion resistance, and ease of fabrication. 1.4542 17 4 ph 630 is recommended for use at temperatures up to 600°F (316°C) for continuous service. However, it can withstand intermittent exposure to temperatures as high as 1100°F (593°C). The material properties such as hardness and tensile strength can be significantly affected by the specific heat treatment condition applied (e.g., H900, H1025, H1075, H1150).

17-4 Stainless Steel Physical Properties

Custom SUS 630 Heat Treatment Conditions

1. H900: Achieved by heating the alloy 17-4 PH stainless steel to 900°F (482°C) for one hour, followed by air cooling. This condition provides the highest strength and hardness.
2. H1025: Achieved by heating the alloy to 1025°F (552°C) for one hour, followed by air cooling. This condition offers a good balance between strength and toughness.
3. H1075: Achieved by heating the alloy to 1075°F (579°C) for one hour, followed by air cooling. This condition provides lower strength but higher toughness compared to H900 and H1025.
4. H1150: Achieved by heating the alloy to 1150°F (621°C) for one hour, followed by air cooling. This condition results in the highest toughness and moderate strength.
