The composition of the rectangular tube

    Carbon

    It exists in all steels and is the most important hardening element.

    Chromium

    It increases the abrasion resistance, hardness, and most importantly, the corrosion resistance, which is considered to be stainless steel with more than 13%. Despite this call, all steel will rust if not maintained properly.

    Manganese

    An important element that helps to generate texture structure, increase firmness, strength, and abrasion resistance.

    Molybdenum

    Carbonization agent to prevent steel from becoming brittle and maintain the strength of steel at high temperature.

    Nickel

    Maintain strength, corrosion resistance, and toughness.

    Silicon

    Help to increase strength. Like manganese, silicon is used to maintain the strength of steel during the production of steel.

    Tungsten

    Enhanced wear resistance. Tungsten is mixed with chromium or manganese in an appropriate ratio to make high speed steel.

    Vanadium

    Enhances anti-wear ability and ductility. A vanadium carbide is used to make striped steel.

The difference between high-quality seamless steel tubes and inferior seamless steel tubes

　　In daily steel procurement, the most irritating and irritating thing is the purchase of inferior seamless steel tubes, which affects product quality. How to identify inferior seamless steel pipe? Here we identify through the following methods: 　　1, poor quality seamless steel pipe surface is prone to scarring. 　　Mainly due to two reasons: 　　(1) There are many impurities in the inferior seamless steel tubes and the materials are not uniform. 　　(2) Inadequate guide equipment for poor quality pipe manufacturers is particularly prone to sticking steel. Contaminated pipes tend to produce scars when they bite into the roll. 　　2, poor quality seamless steel pipe is prone to tube folding. 　　The so-called folding is a variety of fold lines formed on the surface of the seamless steel pipe, and this defect often runs through the entire product. The reason for the folding is that the manufacturer is pursuing high efficiency in order to increase the output. In the production process, ...

GCr15 tube heat treatment process parameters

　　GCr15 Pipe is a high carbon chromium bearing steel with less alloy content, good performance and wide application. After quenching and tempering, it has high and uniform hardness, good wear resistance and high contact fatigue performance. The cold working of the steel is medium in plasticity, the cutting performance is general, the welding performance is poor, the sensitivity to white spots is large, and the temper brittleness is obtained. 　　Chemical composition / element content (%) 　　C: 0.95-1.05 Mn: 0.20-0.40 Si: 0.15-0.35 S: <=0.020 P: <=0.027 Cr: 1.30-1.65 　　The heat treatment system is: steel bar annealing, annealing or oil quenching at 830-840 °C. 　　Heat treatment process parameters: 　　1. Ordinary annealing: heating at 790-810 °C, after the furnace is cooled to 650 °C, air cooling - HB170-207 　　2. Isothermal annealing: 790-810 ° C heating, 710-720 ° C isothermal, air cooling - HB207-229 　　3. Normal fire: 900-920 ° C heating, air cooling - HB270-390 　　4. H...
