Aplication:
(1) Generally used for producing the important parts with high strength and good plastic.
(2) After nitrogen treatment, used for producing the important parts with special performance
requirements, such as shafts, gears, fasteners, bolt of large dia steamer etc.
Alloy steel bars are highly appreciated for its striking fetures such as resilient, fine finish, optimum tensile strength and corrosion resistant. We fabricate these products using optimum quality materials based on well versatile technology in complying with the quality standards. These products are widely used in various construction, automobiles and mechanical parts.
