Stainless Steel 904L Round Bar


ALLOY 904L DESCRIPTION AND APPLICATION;
904L is a high alloy austenitic stainless steel used to weld base metal of similar composition and with its extra low residual elements such as C, Si, S, P, and N improves the weld metal from hot cracking & fissuring. 904L with it 20% Cr, 25% Ni, 4.5% Mo and 1.5% Cu is often found to manufacture or repair processing equipment, tanks, vessels, and piping that handles acetic & sulfuric acids and other chlorides. Also used for joining 317L & 904L to 304 or 316 where added corrosion resistance is needed. Ar + 30% He + 1-3 % CO2 recommended.

The Difference Between Round Bar and Precision Ground Bar

Round bar is exactly as it sounds; a long, cylindrical metal bar. Round bar is available in many different diameters ranging from 1/4″ up to 24″.

Precision ground bar is manufactured through induction hardening. Induction hardening is a non-contact heating process which uses electromagnetic induction to produce the required heat. Centerless ground bar is typically produced by turning and grinding the surface to a specified size.

Precision Ground Bar, also known as ‘Turned Ground and Polished’ shafting, refers to round bars made with fine precision and high-quality steel. They are polished to ensure flawless and perfectly straight surfaces. The manufacturing process is designed for extremely close tolerances for surface finish, roundness, hardness, and straightness which ensures a long service life with reduced maintenance.
