一、 Ductile Iron QT500-7 Nodular cast iron is a material mainly composed of iron. It has medium strength, medium toughness and good machinability. At low temperature, the toughness changes to brittleness, but the low-temperature impact value is high, and it has certain resistance to sudden temperatur... Read More

performance: Generally, cobalt-based superalloys lack coherent strengthening phases. Although the strength at medium temperature is low (only 50-75% of nickel-based alloys), they have higher strength, good thermal fatigue resistance, and thermal corrosion resistance above 980°C. And abrasion ... Read More

Cobalt-based alloy is a hard alloy that can withstand various types of wear, corrosion and high temperature oxidation. It is commonly referred to as cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy (Stellite alloy was invented by American Elwood Hayness in 1907). Cobalt-based alloys are ... Read More

What is a roll: A roll is a tool that uses the pressure generated by a pair or a set of rolls to roll steel and cause plastic deformation of the metal. The rolls are mainly subjected to dynamic and static loads, wear and temperature changes during rolling. Commonly used heat treatment types for ... Read More

Alloy steel with high strength and good chemical stability at high temperatures. It includes two types of anti-oxidation steel (or high-temperature non-skinned steel) and hot-strength steel. Anti-oxidation steel generally requires better chemical stability, but bears lower loads. Hot-strength steel ... Read More
