Stainless Steel 304/304H/304L Nuts

ASTM A193 304 Nuts, 304H Stainless Steel High Tensile Nuts, Stainless Steel 304L Hexagon Coupling Nuts, SS DIN 1.4301 Heavy Hex Nuts Suppliers in India.

Ranfit Metal & Alloys is a known exporter of Stainless Steel 304 / 304L / 304H Nuts, which is ideally suited for home and commercial applications. Stainless Steel 304 Nuts reduces the ferrite content of the steel and has found to be necessary for some chemical processes. Stainless Steel 304L Nuts has high ductility, excellent forming, spinning and drawing properties. Stainless Steel 304H Nuts contains a higher chromium and lower carbon content than other variations. Because of its popularity, the versatile and widely used Stainless Steel UNS S30400 Nuts is found in the manufacturing of several industries. Stainless Steel UNS S30403 Nuts is used as a material of construction up to 1500 Degree F.

Stainless Steel UNS S30409 Nuts are commonly found in petroleum refineries, heat exchangers, boilers, condensers, etc. Stainless Steel 304 Hex Head Nuts is used for service in elevated temperature environments. Stainless Steel 304L Square Nuts has a higher carbon content making the steel more suitable for use in applications where elevated temperatures are present. Stainless Steel 304H Lock Nuts does not require post-weld annealing and so is extensively used in heavy gauge components. Stainless Steel 304 Eye Nuts has the greater carbon content that delivers an increased tensile and yield strength. Stainless Steel 304L Wing Nuts is modified with a Controlled Carbon Chemistry for Increased Strength to 1500 Degree F (816 Degree C).
