Manufacturer of Stainless Steel 904L Plates & Sheets

Combination 904L is a hardenable, martensitic stainless steel that is an alteration of Alloy 410. Like 410, it contains at least 12% chromium, sufficiently adequate to give consumption safe properties. Compound 904L has higher carbon content than Alloy 410 which is intended to advance quality and hardness attributes. It has great flexibility it the tempered condition yet is fit for being solidified up to Rockwell hardness 50 HRC, the most astounding hardness of the 12% chromium grades. Because of its solidifying properties, Alloy 904L is not frequently welded, in spite of the fact that it is conceivable.

Martensitic stainless steels are intended for high hardness and here and there different properties are to some degree bargained. Erosion resistance is lower than the normal austenitic evaluations and their valuable working extent is restricted by their loss of flexibility at below zero temperatures and loss of quality by over-treating at hoisted temperatures. Its best consumption resistance is accomplished when the metal is solidified and surface ground or cleaned.
