441 STAINLESS STEEL Product Description. AK Steel 441 is a nominal 18% chromium (Cr) bearing ferritic stainless steel stabilized with niobium (Nb). AK Steel 441 provides good high-temperature strength that exceeds that of Types 409 and AK Steel 439 stainless steels. AK Steel 441 offers good corrosion resistance in many exhaust gas environments, equivalent to that of Type 439 and AK Steel
4Cr13 (40Cr13) Stainless Steel Datasheet, Properties4Cr13 steel (New name:40Cr13) is a martensitic type stainless steel, which has higher hardness than 3Cr13 steel after quenching. The steel has good mechanical processing performance. After heat treatment (quenching and tempering), it has good corrosion resistance, polishing performance, high strength and wear resistance.
Stainless steel is an alloy of low carbon steel and chromium for enhanced corrosion characteristics. Stainless steel is highly corrosion resistant for the price. Because the anti-corrosive properties are inherent to the metal, it will not lose this resistance if scratched during installation or use.
Q355 Steel, Q355B Q355C Q355D Properties, Composition Q355 steel is a Chinese low alloy high strength structural steel, which replaced Q345, the material density is 7.85 g/cm3. According to GB/T 1591 -2018, Q355 has 3 quality levels:Q355B, Q355C and Q355D. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Strength, 355 is the minimum value of yield strength 355 MPa for steel thickness 16mm, and tensile strength is 470-630
S355J2 Steel PlatesIt is having general corrosion resistance, pitting resistive, stress corrosion cracking, crevice corrosion resistance ability. S355J2 is also a welder friendly and low carbon steel and it readily can be easily welded to other steels. For the low carbon equivalent, it is possessing cold forming property.

XG08 anti-zinc corrosion steel manufacturer steel plate 3) Copper:The copper in the steel base can slow down the pickling speed, but has no harmful effect on the hot-dip galvanizing, and at the same time can improve the corrosion resistance. When manufacturing special-purpose corrosion-resistant galvanized sheets, the copper content is often selected 0.2~0.3% steel grade.
The carbon equivalent of Q345 is less than 0.3%, and it can be said that the weldability is okay (generally, the carbon equivalent of 0.4% increases the sensitivity to cold cracks). So Q345A is usually not warmed up. But when the board is very thick, it needs to be preheated because it cools quickly. Once 20 # steel was welded with J422 (E4303).
