What is hardox 450 steel carbon content steel grade

How to improve the wear resistance of wear-resistant plate, Hardox 450 steel carbon content?1. Grain refinement to promote the increase of dislocation density under stress state.2. Reduce the Mn content to reduce the Austenite Stability of wear-resistant plate and achieve the ability of accelerated work hardening.3. Cr, Mn, V, Ti and other elements are added to improve the wear resistance of the wear-resistant plate, and the carbide is dispersed in austenite to enhance the wear resistance.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for Hardox 450 steel carbon content.

Flat Hardox 450 steel carbon content steel plate, with a small thickness of the plate. Low carbon equivalent, to adapt to automatic submerged arc welding, plasma welding and other Hardox 450 steel carbon content welding process requirements.

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This Hardox 450 steel carbon content method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.
