At the same time of doing well in A573 grade 70 steel sheet production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A573 grade 70 steel sheet technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
41Cr4 (1.7035) material is an alloy structural steel grade commonly used internationally. Its tensile strength, yield strength and hardenability are all higher than that of 40# steel, but it also has certain defects that its weldability is limited and there is a tendency to form cracks. 41Cr4 steel is generally used for more important quenched and tempered parts, such as parts that work under alternating loads, medium speed and medium load parts.
The five advantages of A573 grade 70 steel sheet wear-resistant steel plate can reduce its own weight. The steel plate is designed according to the addition of several required alloy elements. Through the special heat treatment method of steel plate, the strength level of A573 grade 70 steel sheet steel plate is improved to make it have high hardness (wear resistance) corresponding to various specifications. The result is a significant reduction in the weight of the structure.
Ultrasonic flaw detection emits ultrasonic waves to the A573 grade 70 steel sheet steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the A573 grade 70 steel sheet steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. A573 grade 70 steel sheet, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.
