The high chromium and relatively low nickel content of 309 provide good resistance to high-temperature sulfur-bearing atmospheres. 309 has only moderate resistance to carbon absorption and is not suggested for use in highly carburizing atmospheres. At Sankalp Alloys Overseas, we produce high-quality Stainless Steel S30900 Sheets & Plates from superior raw materials procured from vendors of great repute. We have highly qualified and skillful team members who manufacture these Stainless Steel 309 Sheets & Plates to their full potential at any time without compromising on quality and quantity standards.
They are engaged in the production process continually and solve all the associated difficulties, thereby maintaining standards of producing high-quality Stainless Steel 309 Sheets & Plates. The final tests that we conduct after the production process on our Stainless Steel 1.4828 Sheets & Plates check the working efficiency and strength of these plates or sheets. These tests are done under the supervision and guidance of experts, ensuring dimensional accuracy and defect-free products.
Our Stainless Steel sheets and plates exhibit excellent corrosion, oxidation, heat resistance, and higher strength at elevated temperatures. Grade 309 Stainless Steel sheets and plates are available in different sizes and wall thicknesses. That's not all; aggressive pricing marks a differentiating factor for our products in this range. SS 309 Hot Rolled Sheets and Plates are always in demand with different clientele. Our most experienced engineers operate the manufacturing practices so that higher tensile strength and yield capacity are achieved through cold working for SS 309 Cold Rolled Sheets and Plates.
