Product introduction:china steel shot。
Shot is a commonly used metal parts processing materials, steel shot-organized, uniform particle size, surface-treated steel shot metal workpieces can serve to increase the pressure on the metal surface effect can be very good to improve the fatigue resistance of the workpiece . The use of steel shot having to clean metal surface treatment speed characteristics, steel shot and grit proper hardness, good rebound, internal corner angle and complex shape of the workpiece can be uniformly rapid cleaning, surface treatment time shortened improve work efficiency, it is a good surface treatment material.
Shot features and applications:
Shot is a common surface treatment materials, a wide range of steel shot, steel shot for different kinds of raw materials and equipment needed are also different. Here to talk about the main features of the following Shot:
Shot is a high quality wear-resistant materials, steel shot moderate hardness, toughness, good impact resistance and long service life. It has a good rebound when cleaning the workpiece, cleaning speed, low consumption. Shot wide range of use, like the surface of the part surface of castings, forgings and machined parts and in the heat-treated in a variety of fields. General manufacturing, shipbuilding and other steel shot should be used.
Shot technical requirements:
Specifications Grading: S400 ~ S030;
Hardness: 390HV-530HV;
Chemical composition: C: 0.8% to 1.2%, Mn: 0.6% to 1.2%, Si: 0.4% to 1.2%, sulfur and phosphorus: ≤0.05%;
Microstructure: Tempered martensite or tempered troostite;
Density ≥7.0g / cm3;
Defects total ≤10%;
Extraneous matter ≤1%;
Water content ≤0.2%.
Original standard GB6484-86 steel shot was abolished in 1993.
Because iron pills after tempering annealing, uniform surface color was blue, often with a tempered iron pellet posing as steel balls, iron balls life only 50-400 times, severely reduced iron pellet blasting effects, serious damage to the interests of users.
Shot type and use:
S-550 S-460:
Large and medium-sized cast iron, cast steel, forgings, heat-treated pieces, steel, sand steel pipes, rust, and strengthen, forming
S-390 S-330:
Medium, small iron, malleable iron, small pieces of casting products, heat-treated products, steel, steel, steel, structural steel, chains, non-ferrous alloy sand, rust, and strengthen, forming
S-280:
Small cast, small cast product, treatment product, cast aluminum, steel, copper alloy, gold-plated prior to treatment, increase elasticity and toughness
S-230 S-170 S-110:
Stainless steel plate, sheet steel, non-ferrous alloy surface prior to coating process, enhance the flexibility and toughness, wire strengthening treatment.
