With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Not a problem with shop air at all. Also, you never know if the blade, or edge could have become warped during heat-treat. Leaving the blade in the wrap, and plate quenching, prevents you from being able to check for this while the blade is still in a heat range where it can be safely straightened, with out the possibility of cracking.

Recommended filler rods and electrodes for stainless steel 304 is grade 308 stainless steel. For 304L the recommended filler is 308L. Heavy welded sections may require post-weld annealing. This step is not required for 304L. Grade 321 may be used if post-weld heat treatment is not possible. Applications of Stainless Steel 304
In this paper, to investigate the effect of stabilizing heat treatment for decreasing intergrular corrosion in welded AISI 321 steel by SMAW, at first, it was solution heat treatment in 1050C and 3 hours , then it was stabilizing heat treatment in various times and temperatures for creating more chrome carbides which could not be created in first stage.
