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 astm a242 type 1 corten steel H beam, 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.

astm a242 type 1 corten steel H beam, Wear resistant steel plate cutting: plasma cutting, carbon arc, grinding wheel saw can be used to cut large area of steel plate into the required shape. In order to reduce the cold crack of wear-resistant steel plate cutting, the wear-resistant steel plate should be preheated when cutting. The thicker the wear-resistant steel plate is, the higher the hardness is, and the higher the corresponding preheating temperature is. The preheating temperature should not exceed 200.

In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project . S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks. J2 symbol -20 temperature impact test. The client required CEV 0.38%, S≤0.01%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates. After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of astm a242 type 1 corten steel H beam products.
