Daxun is a 17-4 stainless steel sheet supplier in China

Leading Stainless Steel Sheet Suppliers in China

Daxun can provide upon request: Alloy 17-4 (H900, UNS S17400) plates.

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.

خواص مکانیکی

• 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.

17-4PH Grade Stainless Steel Sheets in a Variety of Finishes

Our stainless steel sheets (sometimes called steel sheets) are available in a range of beautiful finishes: brushed finish, 2B smooth finish or 8K mirror finish.

The finished side of each stainless steel sheet we supply is coated with a film. This film is easily peeled off after fabrication or installation and protects the surface of the material from wear and marks. The back side is unfinished.

17-4ph Grade Stainless Steel Sheet is the most commonly used variety. It is easily weldable, formable, and has good corrosion resistance.

We can assist in providing stainless steel sheets in any required size.

To meet your specific requirements, our stainless steel sheets are available in three finishes and a variety of sizes. We can readily provide any custom size you may need with our free unlimited cutting service.

We are able to meet any size needs between 0.3 and 30 mm in thickness and between 50 x 50 mm and 2500 x 1250 mm in size. In addition, we provide free unlimited cutting with every order, using a state-of-the-art cutting machine to precisely meet your requirements.
