How to prevent cracks in SA572 Gr 65 carbon steel material cutting

The carbon content of SA572 Gr 65 carbon steel material carbon structural steel is about 0.05% - 0.70%, some of which can be as high as 0.90%. Carbon structural steel can be divided into ordinary carbon structural steel and high-quality carbon structural steel. Carbon structural steel is mainly used in railway, bridge and all kinds of construction projects. Carbon structural steel SA572 Gr 65 carbon steel material can be used to manufacture all kinds of metal components that bear static load and unimportant mechanical parts and general weldments that do not need heat treatment.

SA572 Gr 65 carbon steel material,Q345R material is a special steel grade for pressure vessels with a yield strength of 340MPa It has good comprehensive mechanical properties and technological performance The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 (16Mn) steel In addition to the increased tensile strength and elongation requirements compared to Q345 (16Mn) steel, it also requires impact toughness Q345R steel plate is currently the most widely used and most used steel plate for pressure vessels in China,SA572 Gr 65 carbon steel material.

SA572 Gr 65 carbon steel material,Laser cutting has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
