Heavy Hex Bolt And Nut

Heavy hex produces extra strength and give material a good grip and marking on products has a easy and convinient way to judge the material. For export purpose heavy hex products are widely used .

Mahesh Enterprises is India’s one of the leading Fasteners manufacturers & Suppliers in 904L. It is a high-alloy austenitic stainless steel with low carbon content. The grade is intended for use under severe corrosive conditions. This has been application proved over many years and was originally developed to resist corrosion in dilute sulfuric acid. It is standardized and approved for pressure vessel use in several countries. Structurally, 904L is fully austenitic and is less sensitive to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. Characteristically, due to the combination of relatively high contents of chromium, nickel, molybdenum and copper 904L has good resistance to general corrosion, particularly in sulfuric and phosphoric conditions.

• Good resistance to pitting and crevice corrosion
• Very good resistance to stress corrosion cracking
• Good resistance to intergranular corrosion
• Good formability and weldability
• Maximum service temperatures of 450 deg.C. (824 deg.F)

• Production and transport of sulfuric acid
• Metal pickling in sulfuric acid
• Production and concentration of phosphoric acid
• Use in seawater, brackish water, condensers, heat exchangers and pipe work in general
• Paper and allied industries
• Gas washing
• Chemical and pharmaceutical industries

• Tensile Strength (KSI) 70
• Yield Strength (KSI) 25
• KSI can be converted to MPA (Megapascals) by multiplying by 6.895.

Alloy 904L is used in the chemical industry to process many chemicals. Some examples are: Acetic acid, Acetylene, Acrylates, Acrylonitrile, Aluminum sulfate, Ammonium phosphate, Ammonium sulfate, Battery acid, Benzene, Butyl acetate, Caprolactum, Cellophane, Citric acid, Nitro phosphate, Oxalic acid, Superphosphate, Tall oil, Tartaric acid and Zinc sulfate.
