What is the difference between SMA490BW corrosion resistant steel strip and medium thick plate

The company's main business: ship plate, SMA490BW corrosion resistant steel strip low alloy plate, automobile steel, high-strength plate, pipeline steel, boiler steel plate, weathering plate, wear-resistant plate, bridge plate, pressure vessel plate, steel plate, steel processing, etc. The company takes the implementation of high-end, SMA490BW corrosion resistant steel strip high-quality, deep processing, strengthening the main business, diversified operation, group operation, enterprise transformation and upgrading as its development strategy, and makes all efforts to be your professional SMA490BW corrosion resistant steel strip steel supplier and partner.

The theoretical weight of seamless steel pipe is the weight per meter of steel pipe calculated by the calculation formula: meter weight = (outer diameter - wall thickness) * wall thickness * 0.02466, in which the outer diameter refers to the farthest distance between the outer walls on both sides of the steel pipe, and the wall thickness is the thickness of the seamless steel pipe wall. The weight per meter of SMA490BW corrosion resistant steel strip seamless steel pipe is calculated by the formula. If you want to get the weight of the whole seamless steel pipe, you should multiply the actual length of the steel pipe.

Stainless steel is resistant to chemical corrosion, air or water and other weak corrosion media. Stainless steel covers ordinary stainless steel and acid resistant steel. SMA490BW corrosion resistant steel strip, Ordinary stainless steel is generally not resistant to chemical corrosion, while acid resistant steel is generally stainless. The use of stainless steel is mainly to maintain the original appearance of the building for a long time.

With the increase of temperature, the yield limit of SMA490BW corrosion resistant steel strip will decrease monotonically, but the tensile strength of SMA490BW corrosion resistant steel strip will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of SMA490BW corrosion resistant steel strip. Near the blue brittleness temperature, the SMA490BW corrosion resistant steel strip strength increases and the plasticity decreases. The elongation and section shrinkage of SMA490BW corrosion resistant steel strip increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The SMA490BW corrosion resistant steel strip, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.
