Product Description

About products

There are many kinds of alloy steels, which are generally divided into low alloy steels (content<5%), medium alloy steels (content 5%~10%) and high alloy steels (content>10%) according to the content of alloy elements; It is divided into high-quality alloy steel and special alloy steel according to quality; According to characteristics and applications, it can also be divided into alloy structural steel, stainless steel, acid resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel and special performance steel (such as soft magnetic steel, permanent magnetic steel, non magnetic steel

Application

This kind of steel is mainly used to manufacture medium speed and medium load parts under the condition of tempering. Or in the quenching, tempering state used for high load and small impact parts, can also be used for large section and surface quenching parts. In the general machinery industry, this steel is used in the manufacture of transmission gear, spindle, mandrel, rotating shaft, connecting rod, worm, motor shaft, generator shaft, crankshaft, flywheel and large and small forgings; In the manufacture of steam turbine, used as the working temperature below 400ºC, diameter within 250mm of the main shaft and hub, thickness of 170mm below the impeller and various important fasteners; In agricultural machinery to manufacture hoe handle, plow shafts and other wear-resistant parts. In addition, it can also be used as thin wall seamless steel pipe. This steel can completely replace 40Cr as tempering steel, or partially replace 40CrNi steel

Packaging	1. by bundles, each bundle weight under 3 tons, for small outer diameter steel bars, each bundle with 4 - 8 steel strips. 2. after making by bundle, covered with Polyethylene waterproof cloth. 3. make black paints painting on each bar, then make bundles
