420 stainless machining warping

how to prevent thick stainless from warping? - Miller

I have to bid on some frames built from 8X8x3/4 304 stainless angle.The problem is that no one makes it.I have talked to the customer,and the engineer will let us fab the angle from plate.My concern is major warping from full pen welds on s.s.this thick.Anyone have any ideas or exp.with this? Thanks.how to prevent thick stainless from warping? - Miller I have to bid on some frames built from 8X8x3/4 304 stainless angle.The problem is that no one makes it.I have talked to the customer,and the engineer will let us fab the angle from plate.My concern is major warping from full pen welds on s.s.this thick.Anyone have any ideas or exp.with this?

How to Control the Warping of Parts in Thin Sheet Metal

The weld wants to shrink as it cools to room temperature,but is restrained from doing so by the adjacent cold base metal.This restraint creates high-residual tensile stress that causes the weld to act like a stretched rubber band,with the workpiece holding the ends (Figure 1).For this reason,when the clamps that hold the workpiece are removed the base metal is allowed to move (or spring H-13,P-20,420ss - Alloy Tool Steel Inc.420 Stainless is usually machined in the annealed condition at speeds of about 50% of those used for a free-machining AISI 1212 material.420 Stainless is sold in the annealed condition.Typical annealed hardness is BHN 192/241 Rc 11.5/22.8.420 Stainless maximum working hardness is BHN 477/500 Rc 49/51.420 Stainless incapable of meeting ASTM FAQs How to Prevent Machined Parts from WarpingApr 08,2015 420 stainless machining warping#0183;Why do machined parts warp in the first place?
