How to protect the S890QL hardness from cracking

Our company is a large S890QL hardness steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special S890QL hardness steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.

How to prevent S890QL hardness, steel plate cutting cracks? 1. Preheat the steel plate before cutting, and the preheating temperature depends on the quality grade and thickness of the steel plate. However, it needs to be heated evenly. 2. The cutting speed is reduced appropriately, but its reliability is not as good as preheating. It is suggested to preheat the cutting belt with flame gun cavitation several times before cutting, and the preheating temperature should reach about 180℃.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The S890QL hardness metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other S890QL hardness alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary S890QL hardness carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.

Classification of S890QL hardness, steel plate, including strip steel:
1. Classified by thickness: (1) thin plate (2) medium plate (3) thick plate (4) extra thick plate
2. Classification by production method: (1) hot rolled steel plate (2) cold rolled steel plate
3. Classification according to surface characteristics: (1) galvanized sheet (hot galvanized sheet, electro galvanized sheet) (2) tin plate (3) composite steel plate (4) color coated steel plate
4. Classification by use: (1) bridge steel plate (2) boiler steel plate (3) shipbuilding steel plate (4) armored steel plate (5) automobile steel plate (6) roof steel plate (7) structural steel plate (8) electrical steel plate (silicon steel sheet) (9) spring steel plate (10) others
