DIN 42CrMo4 steel round bar is generally used in the manufacture of tools which has high strength requirements. This steel is good for large size and important parts,such as axle,gear, connecting rod, gear transmission,turbocharger gear, engine cylinder, spring, oil drill pipe joints and fishing tool. 42CrMo4 steel is sometimes used instead of the high nickel quenched and tempered steels.
42CrMo4 steel round bar is a common Chromium-Molybdenum alloy steel that usually used after quenched and tempered. 42CrMo4 is equal to 1.7225. 1.7225 has better performance than 1.7220 steel due to the carbon and chromium content is higher.
42CrMo4 steel has higher strength and hardenability. This material also has high fatigue strength and good low-temperature impact toughness. The temper brittleness is not obvious.
Heat Treatment:
Quenched and Tempered (+QT) of W-Nr 42CrMo4 Steel
1. Heat DIN 42CrMo4 steel slowly to 880°C;
2. Soak at this temperature then quench in oil;
3. Temper as soon as 42CrMo4 steel reach room temperature (20°C);
4. Heat uniformly to the suitable temperature of 560°C;
5. Withdraw the material from the furnace and cool in the air.
Annealing of 42CrMo4
1. Heat the steel component carefully to 690°C;
2. Cool in the air down to 20°C.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
