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.
Hot rolled Stainless steel rod
Stainless steel rod and bar is heated and rolled through multiple passes in a rolling mill. It has complete specifications and its performance meets standards and requirements.
Cold drawn bright Stainless steel rods
Cold-drawn Stainless steel rods are Stainless steel rods drawn under cold working conditions. They have a smooth surface and can also be polished and ground.

Additional Services
The majority of our inventory is our unique processed bar grade: stainless steel round bars, which are melted to consistent standards to improve machinability and reduce the total cost of each part. Our stainless steel bar processing machinery enables Daxun Alloys to produce to the precise specifications of our customers.
1. Daxun can perform heat treatments on our stainless steel bars. This will depend on the chemistry of the metal being treated. 2. Positive Material Identification (PMI) In some cases, additional Positive Material Identification testing may need to be completed. Daxun Stainless Steel Products can complete this testing in-house or work with an independent laboratory to complete the testing. 3. Ultrasonic Testing (UT) Utilizes high frequency sound energy to inspect and measure stainless steel bar products. This helps with defect detection/evaluation, dimensional measurement, etc.

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.
