Saraweld 12 Bare

Specifications AWS A5 21 2001

Classification ERCOCr B

Description Saraweld 12 Bare rod is slightly harder than Saraweld 6 Bare rod with better abbrasive and metal to metal wear resistance It produces a high hardness cobalt chromium deposit The chromium carbides contained in the deposit provide excellent resistance to many formsof chemical and mechanical degradation including galling It bonds well with all weldable steels induding stainless

Saraweld 1 Bare 

Specifications AWS A5 21 2001

Classification ERCoCr C

Description Saraweld 1 Bare rod has the highest hardness of the standard Saraweld cobalt alloys and is used in elevated temperature wear applications t has a large volume of chromium carbides in a cobalt matrix giving the alloy excellent resistance to abrasion and solid particle erosion It can be machined with difficulty using carbide tools or ground It bonds well with stainless and other weldable grade steels

Saraweld 6 Bare

Specifications AWS A5 21 2001

Classification ERCoCr A

Description Saraweld 6 Bare od proy es resistance to many forms of chemical and mechanical degradation over a wide temperature alloy range t is the most versatile and widely used cobalt with a good balance ofabrasion and impact resistance Particular attributes of Saraweld 6 Bare are t s outstanding anti galling properties high temperature hardness and high resistance to cavitation erosion that resultsin its Wide use as a valve seat material It bonds well to all weldable grade steels and stainless

Saraweld 21 Bare

Specifications AWS A5 21 2001

Classification ERCOCr E

Description Saraweld 21 Bare rod deposits a low carbon austenitic cobalt type alloy with excellent work hardenability high temperature strength and impact resistance These deposits are quite stable during thermal cycling making them a favorite for hot die materials They have good strength and ductility in temperatures up to 2100 F Resistance to galling sel mated corrosion and cavitation erosion make Saraweld 21 Bare is a good choice for valve trim on steam and fluid control valve bodies and seats It bonds well to all weldable steels including stainless
