Kenyelletso ea Sehlahisoa

420 SS(Stainless Steel) terata ea spray ea mocheso ke thepa ea boleng bo holimo e etselitsoeng lisebelisoa tsa ho fafatsa ka arc. 420 SS, e tsebahalang ka ho hanyetsa kutu, ho thatafala haholo le ho se mamelle hantle, ke tšepe ea martensitic e fanang ka tšireletso e matla ea holim'a metsi. Mohala ona o sebelisoa hangata liindastering tse kang petrochemical, tlhahiso ea matla, likoloi le tsa metsing ho matlafatsa ts'ebetso le nako ea bophelo ea likarolo tsa bohlokoa. Thermal spray terata ea 420 SS e loketse lits'ebetso tse hlokang lesela le thata, le sa senyeheng le hanyetsanang le kutu.
