Certifications

CORROSION RESISTANCE:

• Withstands corrosive attacks better than any of the standard hardenable stainless steels.
• Comparable to Alloy 304 in most media.
• Exhibits remarkable corrosion resistance in various industries including chemical, petroleum, dairy, and food processing.
• However, it may experience crevice or pitting attack if exposed to stagnant sea water for prolonged periods.

WELDABILITY:

• Easily welded using most common fusion and resistance techniques.
• Oxyacetylene welding is not recommended.
• Typically, no pre-heating is required.
• The inter-pass temperature should be kept below 248°F.
• Post-weld heat treatment enhances toughness in the weld.

ELEVATED TEMPERATURE USE:

• Demonstrates excellent oxidation resistance up to approximately 1100°F.
• Extended exposure to high temperatures may reduce toughness in precipitation-hardened conditions.

PROCESSING - HOT FORMING:

• For forging, heat uniformly to 2150-2200°F and hold for half an hour per inch of thickness.
• Optimum temperature range for hot forming is 650-900°F while the steel remains austenitic.
• To ensure optimal hardening, re-heat treat forgings at 1875-1925°F.
• Cool forgings below 90°F to achieve grain refinement.

PROCESSING - COLD FORMING:

• Alloy 17-4 is limited to mild operations due to its hardness in the annealed (solution treated) condition.
• For more severe cold working, heat treat the material to condition H1150 to prevent cracking.
• A bend radius greater than 7T is often necessary.
• For improved stress corrosion resistance post cold forming, re-aging at the precipitation-hardening temperature is recommended.

MACHINABILITY:

• Can be efficiently machined in both solution-treated and precipitation-hardening conditions.

Mechanical Properties

• Type 17-4PH stainless steel boasts exceptional mechanical properties. Ideal for applications demanding high strength, hardness, and corrosion resistance, it is also more cost-effective than many high nickel non-ferrous alloys.
