Caliper Overseas is a reliable 307Si (18 8 Mn) Stainless Steel MIG Wire supplier and manufacturer in India providing high-quality welding solutions for those industries which require strength as well as precision. The 307Si (18 8 Mn) stainless steel MIG wire is a specialized austenitic stainless steel MIG wire designed to weld dissimilar metals, high-manganese steels and cracking-susceptible materials. With superior crack resistance and work-hardening properties, it produces strong, ductile welds even in difficult conditions. The "307Si" indicates an altered alloy with increased levels of manganese and silicon for better bead appearance and hot cracking resistance. The "18 8 Mn" refers to its standard composition—18% chromium, 8% nickel, and added manganese.
Made to high industry standards, this wire provides excellent mechanical properties, such as high durability and ductility. It is suitable for high-critical welding applications and is available in tough packaging solutions for your specific requirements. Get in touch with us today for consistent welding performance and timely delivery.
