A Global Leader in Stainless Rod and Round Bar Fabrication Services
Daxun is a globally recognized manufacturer of SS 17-4PH/630 Round Bar/Rod range. We pride ourselves on being a supplier, exporter, and reputable distributor of premium quality bars and rods.
We provide our clients with bars and rods available in various specifications including surface treatment, end finish, dimensions, shapes, and sizes.
SS 17-4PH is a martensitic stainless steel strengthened by precipitation. This alloy is enhanced with elements such as nickel, copper, and chromium. Widely utilized in the aerospace sector for fasteners and structural components, UNS S17400's microstructure is refined during the remelting process, which significantly enhances its toughness.
The 17-4 PH Stainless Steel Round Bar stands out in the manufacturing and engineering sectors due to its exceptional corrosion resistance, high strength, and ease of production. The 'PH' in 17-4 PH denotes precipitation hardening, a heat treatment procedure that enhances the material's mechanical properties.
Hot Rolled Stainless Steel Rod
Our stainless steel rod and bar undergo heating and multiple passes through a rolling mill. These rods have comprehensive specifications and their performance meets all standards and requirements.
Cold Drawn Bright Stainless Steel Rods
Cold-drawn stainless steel rods are created under cold working conditions, resulting in a smooth surface that can also be polished and ground for a refined finish.
Forged Stainless Steel Rod and Bar

- Comparable to the renowned Alloy 304 in the majority of environments.
- Exhibits remarkable corrosion resistance in chemical, petroleum, dairy, and food processing industries.
- Vulnerable to crevice or pitting attacks when exposed to stagnant seawater over prolonged periods.
WELDABILITY:
- Can be welded successfully by most common fusion and resistance techniques.
- Oxyacetylene welding is not recommended.
- Pre-heating is generally unnecessary.
- Inter-pass temperature must be carefully controlled, limited to 248°F.
- Achieve superior toughness in welds through complete heat treatment processes.
ELEVATED TEMPERATURE USE:
- Demonstrates excellent oxidation resistance up to 1100°F.
- Prolonged exposure to high temperatures may diminish toughness in precipitation hardened conditions.
PROCESSING - HOT FORMING:
- For effective forging, uniformly heat to 2150-2200°F and hold for half an hour per inch of thickness.
- Ideal hot forming temperature is between 650-900°F while maintaining the austenitic state.
- To prepare for hardening, re-heat treat the forgings at 1875-1925°F.
- Ensure grain refinement by cooling forgings below 90°F.
PROCESSING - COLD FORMING:
- Alloy 17-4 is best suited for mild operations in its annealed (solution treated) state due to its inherent hardness.
- For severe cold working, heat treat to condition H1150 to prevent potential cracking.
- A bend radius exceeding 7T is typically required.
- Re-aging at the precipitation-hardening temperature post cold forming is recommended to enhance stress corrosion resistance.
MACHINABILITY:
- This alloy can be efficiently machined in both solution-treated and precipitation-hardened conditions.
Mechanical Properties
- Type 17-4PH stainless steel offers exceptional mechanical properties, combining high strength and hardness with excellent corrosion resistance. It is an economical choice over many high-nickel, non-ferrous alloys for demanding applications.
