Short answer: Hardfacing deposits a wear-resistant alloy onto a softer, tougher base metal so only the surface takes the abuse — extending the life of valves, digger teeth, rolls and pump parts far more cheaply than making the whole part from a solid exotic alloy.

What Hardfacing Is
Hardfacing (or weld overlay) lays a thin, hard, wear-resistant layer on a load-bearing base. It lets you combine a cheap tough substrate with a premium surface — our Cobalt Alloy Supplier (Stellite) and Wear Resistant Steel Supplier ranges are the usual donors. Filler choice follows Welding Consumables Guide.
Alloys & Where They Win
Stellite 6 (cobalt-chromium) resists wear and heat for valve seats and screws; iron-chromium-carbon carbide overlays fight abrasion on buckets and digger teeth; nickel-base hardfacings resist erosion in slurry and pumps; tungsten carbide survives the severest gouging in drills and mills; austenitic manganese absorbs impact on rails and jaws. Grade families are explained in Градации нержавеющей стали с пояснениями.
Process & Quality
Overlay is applied by MIG, TIG, submerged-arc or plasma transferred arc, then finished by grinding. Preheat and interpass control avoid cracking on the base; welding detail is in How To Weld Stainless Steel and surface prep in Metal Surface Treatment Guide. Every lot ships with a mill certificate per Mill Test Certificate Guide.

Часто задаваемые вопросы
Hardfacing (weld overlay) deposits a wear-resistant alloy onto a softer base metal so only the surface takes abrasion, heat or impact — extending part life cheaply.
It depends on the wear: Stellite for heat-plus-wear, iron-chromium-carbide for abrasion, tungsten carbide for severe gouging, manganese steel for impact.
Usually yes for cost — you get the premium surface where it matters on a cheap tough base, instead of making the whole part from an expensive alloy.
Yes. HXSCO supplies hardfaced valves, seats, digger teeth and rolls in Stellite, carbide and wear-steel with mill certificates.
