Stainless Steel Round Bar

Stainless Steel Bar is a free machining chromium-nickel austenitic steel with good strength and good corrosion resistance, as supplied in the annealed condition with a typical brinell hardness of 190.

Characterised by excellent machinablity and non galling properties due to its higher sulphur content, which has the effect of lowering slightly its corrosion resistance. It is however, fairly resistant to general atmospheric corrosion, general foodstuffs, sterilizing solutions, dyestuffs, most organic chemicals, plus some inorganic chemicals. But has very limited resistance to acids.

It cannot be hardened by thermal treatment, but strength and hardness can be increased substantially by cold working, with susequent reduction in ductility.

It is used primarily for production runs involving extensive machining, or complex parts requiring excellent machinability.

Applications

Automatic screw machines

Conveyor systems

Architectural Components,

Food Processing Equipment,

Dairy Equipment,

Dying Industry,

Hardware and Kitchenware manufacturing and allied industries.

Commonly used to manufacture Bolts and Nuts, Bushes, Gears, Shafts, Valve Bodies and Fittings etc.

Stainless steel grade 440A is a high carbon martensitic stainless steel that possesses good strength, moderate corrosion resistance, and excellent hardness and wear resistance. stainless steel grade 440A can be easily machined in the annealed condition. Carbide or ceramic tooling is recommended for performing machining. Chip breakers enable easy handling of tough stringy chips.

Equivalent materials to grade 440A stainless steel are given below.

AISI 440A             AMS 5631            AMS 5632            ASTM A276         ASTM A314

Carbon Steel Forged Hollow Bar - Stainless Steel Forged Hollow Bar - Mild Steel Forged Hollow Bar - The Forged Hollow Bars process starts with an ingot cut that is pressed to make a preform, followed by a hole punched on the center of the preform. Then, by using a mandrel, the material is expanded until the desired dimensions are reached. Additionally, we produce hollow tubes using the back-extrusion process. In this process, the preform is forced to flow through a die in the opposite direction of the tool.
