With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
40Cr steel is a Chinese alloy steel, hardness: 207 HBW, chemical composition & mechanical property are equivalent to US ASTM, Germany DIN
40Cr steel is a medium carbon quenched and tempered steel. Normalizing can promote the spheroidization of the microstructure and improve the cutting performance of the roughcast whose hardness is less than 160HBS. In the tempering temperature 550 ~ 570 , the steel has the best comprehensive mechanical properties.
40Cr steel is a kind of Chinese alloy steel, and one of the most widely used steel grades in China. For more information, please see 40Cr steel properties, specification and equivalent . Does Chinese spam, the worst kind.

They differ in what kind of metal they are comprised off and thereby by their properties. Zinc alloys use Zinc as the basis (brass is the most known Zinc alloy; alpha brass contains 35% Zinc and 65% Copper).
Most commonly, the phrase "alloy steel" refers to low-alloy steels. Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type).
20Cr Alloy Structure Steel -China Steel Grade Standard GB/T 3077. First quenching heated slowly to 880C, Then after adequate soaking at this temperature quench in oil or water. Temper as soon as tools reach room temperature. Second quenching heat to 780-820C then quenching in oil or water.
Carbon steel is a popular choice for rough use knives. Carbon steel used to be much tougher, much more durable, and easier to sharpen than stainless steel. They lack the chromium content of stainless steel, making them susceptible to corrosion. Carbon steels have less carbon than typical stainless steels do, but it is the main alloy element.
The standard has revised GB/T 3077-1988 The Technical Conditions of Alloy Structure Steel. There have been some changes in this nationals standard over its previous edition in the following technical aspects: - Change the name of the standard to Alloy Structure Steel;
