Kalpatru is a renowned manufacturer of SS 347 / 347H Fasteners, which generally has a higher corrosion resistance compared to the austenite steels. Stainless Steel 347 Fasteners has excellent resistance to pitting, stress corrosion cracking and to oxidizing atmospheres. Stainless Steel 347H Fasteners is used in a variety of environments from moderately oxidizing to strong reducing conditions. SS 347 Fasteners is a fully austenitic advanced corrosion-resistant alloy that offers resistance to both aqueous corrosion and attack at elevated temperatures. SS 347H Fasteners provides exceptional resistance to general corrosion, pitting, crevice corrosion, intergranular attack, and stress corrosion cracking. The high chromium content of 347 Stainless Steel Fasteners gives it good resistance to wet corrosion by oxidizing media, such as nitric acid and ferric and cupric salts. 347H Stainless Steel Fasteners is a solid solution strengthened, nickel-molybdenum alloy, typically used in extreme reducing conditions. The high molybdenum content in Stainless Steel UNS S34700 Fasteners gives the alloy excellent resistance to hydrochloric acid over a wide range of concentrations and temperatures. Stainless Steel UNS S34709 Fasteners also shows good resistance to hydrogen chloride, sulfuric acid and phosphoric acids. Stainless Steel WNR. 1.4550 Fasteners has excellent resistant to pitting and stress corrosion cracking in the heat–affected zone. Stainless Steel WNR. 1.4961 Fasteners also has yield strength, which is perhaps double that of conventional austenitic steels.
