hardox 450 astm equivalent Tensile Strength

For S420NL weldable fine grain structural steel plate, it is produced under specification EN 10025-3. The yield strength of S420NL plate shall be above 420Mpa for the thickness below 16 millimeter, 400MPa min. for thickness below 40mm, 390MPa min. for thickness below 63mm. The tensile strength for thickness below 100mm of this steel grade S420NL shall be within 520-680Mpa. For the Mill test certificates of steel S420NL,Hardox 450 astm equivalent, our mill would like to issue format according to EN 10204 3.1.

The five advantages of Hardox 450 astm equivalent 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 Hardox 450 astm equivalent 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.

Tempering the important Hardox 450 astm equivalent welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve Hardox 450 astm equivalent strength, plasticity and toughness.
