About H11 Tool & Alloy Steel Square Bars
IMI Alloys India LLP is a well-known distributor and manufacturer of H11 Tool & Alloy Steel square Bars. These bars are favored and insisted due to red hardness. It also impacts toughness and high strength. These square bars are in different sizes, specifications, shapes, and standards further modified to adapt to the applications needed by the buyer on demand. Our bars are obtainable, and the most used types are forged, hot worked, cold worked and threaded, and other types. Our bars are useful in shot gripper dies and extrusion tooling. In addition, fundamental aerospace parts similar to aircraft dart components are largely commenced to square bars.
IMI Alloys India LLP manufactures H11 Steel Square bars useful in high-temperature system applications. It excellently resists corrosive media and holds against decay in acid-containing media. Our bars oppose exhaustion cracking, as well as crevice at elevated temperatures. It is free from intergranular corrosion and protects the surface from pitting. Our square bars provide a conductivity of heat and electro potential. In addition, our bars are anti-corrosive that affords protection from different reducing media.
