Manufacturer, Supplier & Exporter of 420 Stainless Steel Shim

Riddhi Siddhi Impex is a well-established manufacturer and domestic supplier of 420 Stainless Steel Shim across India. Known for its superior hardness, polishability, and wear resistance, Grade 420 stainless steel is a high-carbon, martensitic stainless steel that offers excellent mechanical strength. These properties make it ideal for industrial shimming applications requiring resistance to impact and abrasion.

Our 420 Stainless Steel Shims are manufactured using high-quality raw materials under strict quality control protocols. The shims are produced in a range of thicknesses and finishes such as cold rolled, annealed, and mirror-polished. With excellent machinability and heat-treatable properties, these shims are extensively used in the production of surgical tools, cutlery, valves, fasteners, dies, and automotive components.

Riddhi Siddhi Impex offers custom sizes and shapes for 420 SS Shims to suit specific industrial needs. With in-house slitting, shearing, and finishing capabilities, we can provide sheets and coils with tight tolerances, perfect flatness, and burr-free edges.
