Cause analysis of cracks in 42crmo4 steel density

Boiler steel plates are mainly used to manufacture various boilers and important accessories. Because the boiler steel plate is working under medium temperature (below 350°C) and high pressure, in addition to high pressure, it is also subject to impact, fatigue load and water and gas corrosion. It is required to ensure a certain strength and also have good welding and cold bending performance. Common grades: Q245R, A515 Grade 55, A515 Grade 60, 42crmo4 steel density, A516 Grade 65, A516 Grade 70.

The thickness of cold-rolled steel sheets is generally relatively small, and the thickness of hot-rolled plates can be larger. The surface quality, appearance, and dimensional accuracy of cold-rolled steel sheets are better than those of hot-rolled plates, and the thickness of cold-rolled steel sheets can be rolled as thin as about 0.18mm. 42crmo4 steel density, Hot-rolled plates has high strength, good toughness, easy processing and good weldability and other excellent properties.

Laser cutting, it is a specific way of cutting 42crmo4 steel density steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting 42crmo4 steel density speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.

Over the years, the company has maintained long-term stable business relationships with major domestic steel mills and foreign steel companies. The company's main boiler and pressure vessel steel plates, low alloy high-strength steel plates, wear-resistant steel plates, corrosion-resistant steel plates, 42crmo4 steel density bridge steel plates , strucural teel plates, steel plates for alloy structures, mold steel plates, steel plates for shipbuilding and production platforms, composite steel plates, steel plates for oil and gas pipelines.
