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

Features and applications

It has high strength and toughness, its strength is higher than that of 35 steel, its mechanical properties are basically similar to that of 30Cr, and its hardenability is slightly higher than that of 30Cr. It is usually used in the quenched and tempered state or after normalizing. It is used to manufacture important parts that work under wear and friction conditions or great impact loads, such as shafts, small shafts, balance levers, rocker bars, connecting rods, bolts, nuts, gears and various rollers.

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
20 feet container contains dimension	Length under 6000mm
40 feet container contains dimension	Length under 12000mm
By bulk vessel	Freight charge is low by bulk cargo, and large heavy sizes can not be loaded into containers can shipping by bulk cargo
