为提高的耐腐蚀性能,济南镀锌管对一般钢管进行镀锌。镀锌钢管分热镀锌和电钢锌两种,热镀锌镀锌层厚,电镀锌成本低,所以有了镀锌钢管。

In order to improve the corrosion resistance, galvanized steel tubes are galvanized by Ji'nan galvanized pipe. The galvanized steel pipe is divided into two kinds of hot dip galvanizing and electric steel, the hot galvanizing layer is thick and the cost of galvanizing is low, so the galvanized steel pipe is made.

1、碳;含碳量越高,钢的硬度就越高,但是它的可塑性和韧性就越差。

1, carbon; the higher the carbon content, the higher the hardness of the steel, but the worse the plasticity and toughness of the steel.

2、硫;是钢中的有害杂物,含硫较高的钢在高温进行压力加工时,容易脆裂,通常叫作热脆性。

2, sulfur; it is a harmful impurity in steel. High sulphur steel is brittle cracking when it is processed at high temperature. It is usually called thermal brittleness.

3、磷;能使钢的可塑性及韧性明显下降,特别的在低温下更为严重,这种现象叫作冷脆性.在优质钢中,硫和磷要严格控制,在低碳钢中含有较高的硫和磷,能使其切削易断,对改善钢的可切削性是有利的。

3, p; can make the plasticity and toughness of the steel decreased significantly, especially at low temperature is more serious, this phenomenon is called cold brittleness. In high-quality steel, to strictly control the sulfur and phosphorus, sulfur and phosphorus containing high in low carbon steels, can make the cutting easily broken, beneficial to the improvement of the steel machinability is the.

4、锰;能提高钢的强度,能消弱和消除硫的不良影响,并能提高钢的淬透性,含锰量很高的高合金钢具有良好的耐磨性和其它的物理性能。

4, Mn; can improve the strength of steel, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel, manganese content of high alloy steel has good wear resistance and other physical properties.

5、硅;它可以提高钢的硬度,但是可塑性和韧性下降,电工用的钢中含有一定量的硅,能改善软磁性能。

5, silicon; it can improve the hardness of the steel, but the plasticity and toughness decrease, the steel in the electric steel contains a certain amount of silicon, which can improve the soft magnetic properties.

6、钨;能提高钢的红硬性和热强性,并能提高钢的耐磨性。

6, tungsten, can improve the steel hardness and heat strength, and can improve the wear resistance of the steel.

7、铬;能提高钢的淬透性和耐磨性,能改善钢的抗腐蚀能力和抗氧化作用。

7, chromium, can improve the hardenability and wear resistance of steel, and can improve the corrosion resistance and oxidation resistance of steel.
