Applications of low carbon steel shot

　　S-2.5, SS-2.0 Large castings, steel castings, steel structural parts, large forgings, sand cleaning for heat treatment, rust removal and oxidation surface cleaning, etc. SS-1.7, SS-1.4 Sand cleaning for large and medium-sized castings, castings , heat treatment to remove oxide scale, rust removal and surface oxidation of steel plates, shaped steel and steel components SS-1.2, SS-1.0 Sand cleaning of small and medium-sized castings, rust removal of forgings, heat treated parts, steel plates, steel pipes, shaped steel and structural steel parts Strengthening, coating, surface treatment before painting and stone cutting SS-0.8, SS-0.6 Small castings, forgings heat-treated parts, aluminum-copper alloy castings, steel plates and strips, steel pipes, etc. Sand cleaning to remove oxide scale, surface strengthening of spring chains And grinding and processing stone cutting. SS-0.5, SS-0.3 are used for sand and rust removal, spring strengthening, and surface treatment before spraying of alloy castings, thin plates, strips, and small stainless steel castings to increase roughness and enhance adhesion. Chemical composition: C: 0.08%-0.30% Si: 0.10%-0.25% Mn: 0.35%-1.50% S: ≤ 0.030% P: ≤ 0.030% Other alloys: Cr, Mo, Ni, B, AI, Cu Hardness: HRC40-56 metallographic structure: composite structure combining martensitic and bainite Note: 1. Add harmful elements to 0.03% to increase strength and extend service life 2. Add alloy elements to make alloy steel with excellent properties 3 . Appropriate hardness ensures shot blasting efficiency 4. Duplex structure ensures high strength
