ASTM A276 Ferritic S32760 Hex Bar, Flat Bar, Forged Bar, Square Bar Super Duplex Steel Austenitic S32750 / S32760 Bright Bar Stockist and Supplier in Mumbai India.
Table of Content
High-strength stainless steels, Super Duplex Steel S32750 Round Bar and Super Duplex Steel S32760 Round Bar re made to withstand harsh conditions. These grades combine the benefits of both austenitic and ferritic stainless steels offering excellent strength and corrosion resistance. Chromium, molybdenum, nickel and nitrogen combines to give S32750 Super Duplex Round Bar exceptional resistance to pitting and stress corrosion cracking. With the addition of tungsten for improved corrosion resistance in saltwater and chloride-rich environments S32760 Super Duplex Round Bar provides comparable performance. Their mechanical strength is remarkable, with high yield and tensile strength, along with good ductility and hardness control. Preston Pipes and Alloys supplies these bars in precise chemical compositions and ensures compliance with mechanical property standards for demanding industries.
These bars have key features that make them stand out. They deliver much higher strength than standard stainless steels. Even in harsh, acidic or salty conditions, they are immune to pitting, cracking, and crevice corrosion. They maintain stability up to about 300°C and have low thermal expansion, making them reliable in fluctuating temperatures. Industries use them for offshore oil and gas equipment, subsea pipelines, heat exchangers, marine hardware, chemical plant systems, power plant components, pulp and paper machinery and food processing equipment. While S32760 performs even better in demanding chemical or marine applications because of tungsten enhancement, S32750 is best suited for high-strength chloride-exposed work.
We offer these bars in sizes from 6 mm to 350 mm diameter and lengths from 1 to 6 meters, with custom cuts available. Forms include round, square, hex, billet and forging in finishes like bright, polished or black. Manufacturing starts with melting selected scrap and alloying elements in an electric arc furnace. Refining follow through argon oxygen decarburization. Hot working shapes the billets into bars, and cold working can refine dimensions and improve strength. Heat treatments like solution annealing improve toughness and corrosion resistance. Every bar is finished to meet dimensional needs then tested for quality before packaging.
Every batch of Super Duplex S32750 Bar and Super Duplex S32760 Bar passes strict testing. Checks include tensile, hardness, and elongation tests, chemical analysis, PMI, pitting resistance, intergranular corrosion, micro and macro exams, flattening and flaring tests. Bars are packed with care wrapped in poly bags, secured in wooden cases, and cushioned with bubble wrap. To satisfy the needs of the customer, custom packaging is available. As a leading UNS S32750 Round Bar Supplier we provide dependable products that can be used for crucial operations because of their emphasis on quality and handling.
