SS 304H Square Bar

We are Recognized as the Prominent Manufacturer, Exporter and Supplier of a broad assortment of Stainless Steel 304h Square Bar. The offered SS 304h Square Bar is designed with utmost precision in conformity with the international quality standards.

304h Stainless Steel Square Bar can be categorically said that steel bars are one of the core components of any manufacturing industry or for that matter any industry that relies on machineries. versatile applications in automotive, textile, fabrication, construction, cement, ship building, paper and pulp, defence, heavy earth moving equipments or aerospace.

Grade 304h Stainless Steel is the standard “18/8” stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304h enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special “304hDDQ” (Deep Drawing Quality) variants.

17-4PH Stainless Steel Sheet, Coil and Plate – AMS 5604, UNS S17400

17-4 PH is a martensitic, chromium-nickel-copper precipitation-hardening stainless steel. 17-4 PH stainless steel is capable of attaining a wide range of strength and toughness properties depending on the precipitation or aging temperature used in hardening.  Its valuable combination of  high strength, good corrosion resistance and toughness in both base metals and welds gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. High strength is maintained to approximately 600°F (316°C). This material has good resistance to stress corrosion cracking in the lower strength conditions.

310/310S Stainless Steel

Our  inventory now includes 310/ 310S Plate and Processed Flat Bar (Alloy 310 UNS S31000 / Alloy 310S UNS S31008), ideally suited for high-temperature applications such as heat treatment and chemical processing equipment. Alloy 310 is an austenitic stainless steel that combines excellent high temperature properties with good ductility and weldability. It is typically used for elevated temperature applications as its high chromium and nickel content provide solid corrosion resistance, excellent resistance to oxidation, and superior strength in temperatures up to 2100°F. Due to its high chromium and nickel content, it is superior to 304 or 309 stainless in most environments.
