The industrial demand, as well as the development of technological innovation, the hammer industry continues to develop. Hammerhead manufacturers have responded to different industrial needs and strictly produced a batch of hammerheads with different properties. Each type of hammerhead is different in terms of wear resistance and hardness. Which high-chromium composite hammer is made?
As we all know, high-chromium cast iron is a wear-resistant material with excellent anti-wear properties, but it has low toughness and is prone to brittle fracture. In order to ensure the safe operation of high-chromium cast iron hammers, high-chromium composite hammers have emerged, which have been improved in terms of wear resistance and toughness.
This type of hammerhead casts high-chromium cast iron into the head of a high-manganese steel or low-alloy steel hammer, or uses a high-chromium cast iron in the working part of the hammer and a carbon steel in the hammer handle to combine the two to make the hammerhead. The head has high hardness, and the hammer handle has high toughness, fully exerts the respective advantages of the two materials and overcomes the disadvantages of the single material, and satisfies the performance requirements of the hammer head.
However, the high chromium composite hammer has a complex manufacturing process and strict process requirements. According to the preliminary report of the previous few years, the overall performance of the three barrels of oil reversed the downward trend, among which, CNPC’s net profit increased by 5.6% year-on-year, and CNOOC’s net profit increased by 7.9% year-on-year. The industry’s momentum is generally positive.
