Over the years, our Hardox 450 steel grade steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge Hardox 450 steel grade steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

Although both HSLA steel plate and carbon steel plate belong to carbon structure and low alloy structure steel, there are some differences. First of all, Hardox 450 steel grade, HSLA steel plate and carbon steel plate differ in strength, hardness and use. In terms of strength, the strength of HSLA steel plate is higher than carbon steel plate. In terms of hardness, the hardness of HSLA steel plate is also higher than that of carbon steel plate. And in the scope of use, the advantages of HSLA steel plate are more prominent, so the scope of HSLA steel plate use is more extensive than that of carbon steel plate.

Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience or combined with the results of the impact test of notched specimens. In order to meet the very strict requirements of certain applications, some Hardox 450 steel grade, low-alloy high-strength steels produced have excellent notch toughness. For example, controlled hot rolling technology is usually used to produce low-alloy high-strength steel plates for the manufacture of welded line pipes. Such steel pipes need to meet the requirements of relevant standards for notch toughness.

As the thickness and hardness of Hardox 450 steel grade increase, the tendency to crack at the cutting edge increases. In order to prevent the Hardox 450 steel grade from cutting cracks, preheating should be carried out before Hardox 450 steel grade cutting. Special attention should be paid to preheating to make the entire Hardox 450 steel grade interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole Hardox 450 steel grade cannot be preheated, the partial preheating method can be used instead.
