H G Metal is a known distributor of SS 304 Patta Patti, which is the most common grade and known as the classic 18/8 (18% chromium, 8% nickel) stainless steel. Buy 304 Stainless Steel Patta Patti at very competitive price from us. ASTM A240 Type 304 Patta Patti was originally called 18-8 which stood for its chromium and nickel content. ASTM A240 SS 304 Patti also contains 18 – 20% chromium and 8-10.50% nickel, and lesser quantities of some other elements. ASTM A240 Stainless Steel 304 Patti is used in kitchen benches, sinks, troughs, equipment, and appliances. ASME SA 240 Type 304 Patta has good mechanical properties and corrosion resistance. The carefully controlled chemical composition of ASME SA 240 SS 304 Patti enables them to be deep drawn more severely than AISI types 301, without intermediate annealing. In the annealed condition, ASME SA 240 Stainless Steel 304 Patta Patti is essentially non-magnetic and becomes slightly magnetic with the application of cold work.304 SS Pattahas excellent low-temperature properties and responds well to hardening by cold working. Stainless Steel UNS S30400 Patta Patti is an austenitic alloy, which means that a nonmagnetic solid solution of ferric carbide or carbon in iron is used in giving this stainless steel its corrosion-resistant properties.
Stainless Steel DIN 1.4301 Patta Patti exhibits good machinability and have excellent weld-ability characteristics with or without the addition of filler metals. SS DIN 1.4301 Patta Patti is used in all industrial, commercial and domestic fields because of its good corrosion and heat resisting properties. As a result, 304 SS Patta Patti is often used for a variety of household and industrial applications such as screws, machinery parts, car headers, and food-handling equipment. Grade 304 Stainless Steel Patti is also used in the architectural field for exterior accents such as water and fire features. Grade 304 SS Patta Patti is as well used in moisture separator re-heaters, feed-water tubes, stator bars, heat exchangers, and more. In short, everything from stovetops to ball point pen barrels to flatware to fasteners has been fabricated from Type 304 Stainless Steel PattaLower carbon in Type 304 SS Patta Patti minimizes chromium carbide precipitation due to welding and its susceptibility to inter-granular corrosion.
AISI Type 304 SS Patta Patti has excellent toughness, even down to cryonegic temperatures which are defined as very low temperatures. The balanced austenitic structure of AISI 304 SS grade 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.
