Values for the SKIN-PASS condition
What is 1.4607 SKIN-PASS?
1.4607 SKIN-PASS is 1.4607 supplied in the SKIN-PASS condition — slightly higher yield and flatter, stiffer strip for roll-formed or stamped parts with limited stretch. 1.4607 SKIN-PASS has a yield strength of 400 MPa (58 ksi) and a tensile strength of 540 MPa (78.3 ksi) — stronger than 57% of stainless steel grades. Elongation at break is 18% and the elastic modulus is 220 GPa (31.9 Msi). 1.4607 SKIN-PASS has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,450°C (2,642 °F).

Working with 1.4607 SKIN-PASS
Is 1.4607 easy to machine?
Machines like 430/441 — gummy but low work hardening; use sharp positive-rake carbide, rigid setup, generous coolant and moderate speeds with heavy feeds to break chips.
Can 1.4607 be welded?
Excellent — Nb+Ti stabilization prevents HAZ sensitization and limits grain growth; TIG/MIG/laser with Ar (+He), low heat input, matching stabilized or 309L/430Nb filler, no post-weld anneal required.
Can 1.4607 be formed, bent or molded?
Good roll forming, bending and moderate deep drawing; lower r-value and elongation than austenitics, so allow larger bend radii, avoid severe stretch forming and beware of ridging/roping on drawn faces.
What surface finishes work on 1.4607?
Pickle and passivate after hot work; brushed, 2B or BA finishes take well and it can be electropolished, but it is not anodizable and should be kept free of embedded carbon-steel particles.
