If your application requires certain physical attributes, please speak with a Daxun sales specialist to confirm this material matches your specifications.
Global leader in stainless rod and Round Bar fabrication services
Daxun is a global manufacturer of SS 17-4PH/630 Round Bar/Rod range. We are a supplier, exporter and reputable distributor of high quality bars and rods.
We offer our customers bars and rods in various parameters including surface treatment, end finish, dimensions, shapes and sizes.
SS 17-4PH is a martensitic stainless steel that is hardened by precipitation. However, the alloy includes alloying elements such as nickel, copper and chromium. The alloy is widely used in the aerospace sector for fasteners and other structural components. UNS S17400 has a microstructure obtained from the alloy during the remelting process. The improved structure in the alloy improves its toughness.
Stainless steel 17-4 PH Round Bar is a popular and adaptable material in the manufacturing and engineering industries due to its excellent corrosion resistance, high strength and ease of production. The “PH” in 17-4 PH refers to precipitation hardening, which is a heat treatment procedure that improves the mechanical properties of the material.
Our network of service centers stock stainless steel bar products for fast, ready supply of bar in common sizes and alloys.We also produce custom-sized stainless steel rods and can arrange inventory schedules for quick turnaround in a timely manner if quantities are below factory minimums.Daxun Alloys stocks stainless steel round bars with diameters ranging from 1/16″ to 26″. Round bars are available in nearly every grade of stainless steel, including 302, 303, 304/L, 309/S, 310/S, 316/L, 317/L, 321, 321/H, 347, 347H, 410, 416, 420, 440C, 17-4PH, Duplex 2205, and Alloy 20. Heat treated stainless steel round bars are offered in 17-4PH, H900 temper (on request), H1025, H1150, Double H1150, and H1150M. Other heat-treated tempers can be manufactured upon request. We stock the following 400 series stainless steels: 410, 430, and 416. We also carry 303, 304, and 316/L precision and bearing quality stainless steel round bars.

CORROSION RESISTANCE:
- Withstands corrosive attacks better than any of the standard hardenable stainless steels.
- Comparable to Alloy 304 in most media.
- Corrosion resistant in some chemical, petroleum, dairy, and food process industries.
- Subject to crevice or pitting attack if exposed to stagnant sea water for any length of time.
WELDABILITY:
- Successfully welded by most common fusion and resistance methods.
- Should not be joined by oxyacetylene welding.
- Generally no pre-heating required.
- Inter-pass temperature must be limited to 248°F.
- Better toughness is obtained in the weld after a complete heat treatment.
ELEVATED TEMPERATURE USE:
- Excellent resistance to oxidation to approximately 1100°F.
- Long-term exposure to elevated temperature can result in reduced toughness in the precipitation hardened conditions.
PROCESSING – HOT FORMING:
- To forge, heat uniformly to 2150 / 2200°F and hold for half hour per inch.
- Preferred temperature range for hot forming is at 650-900°F, while the steel is still austenitic.
- To ensure the best condition for the hardening operations, the forgings must be re-heat treated at 1875-1925°F.
- Cool forgings to below 90°F to ensure grain refinement.
PROCESSING – COLD FORMING:
- Alloy 17-4 is limited to mild operations since in the annealed (solution treated) condition the material is hard.
- For severe cold working the material should be heat treated to condition H1150. This will help prevent possible cracking.
- Bend radius in excess of 7T is often required.
- To improve stress corrosion resistance after cold forming, re-aging at the precipitation-hardening temperature is recommended.
MACHINABILITY:
- Can be machined in both solution-treated and precipitation-hardening conditions.
Mechanical Properties
- Type 17-4PH stainless steel has excellent mechanical properties. For applications requiring high strength and hardness as well as corrosion resistance, Type 17-4PH stainless is an outstanding choice, and it is more cost effective than many high nickel non-ferrous alloys.
