耐磨板中的碳提高了钢的硬度和强度还有耐磨性能

HARDOX500耐磨板耐磨板的力学性能主要取决于碳的质量分数及热处理状态.从选材角度来看,碳的质量分数越低,其强度、硬度越低,塑性、韧性越高,反之亦然。锰的质量分数较高的耐磨板,强度、硬度也较高。

The mechanical properties of HARDOX500 wear resistant plate mainly depend on the mass fraction of carbon and heat treatment state. From the perspective of material selection, the lower the mass fraction of carbon, the lower the strength and hardness, and the higher the plasticity and toughness, and vice versa. The strength and hardness of wear-resistant plate with higher manganese content are also higher.

一般情况下,08一25钢属低碳钢.这些钢板具有良好的塑性和韧性,强度、硬度较低,其压力加工性能和焊接性能优良,主要用于制造冲压件、焊接件和对强度要求不高的机器零件;当对零件的表面硬度和耐磨性要求较高,同时整体要求高韧性时,可选用15钢、20钢经渗碳、淬火加低温回火后使用;

In general, 08-25 steel belongs to low carbon steel. These steel plates have good plasticity and toughness, low strength and hardness, and excellent pressure processing performance and welding performance. They are mainly used for manufacturing stamping parts, welding parts and machine parts with low strength requirements. When the surface hardness and wear resistance of parts are higher, and the overall requirements are high toughness, 15 steel and 20 steel can be selected It can be used after carburizing, quenching and low temperature tempering;

30一55钢属于中碳钢,具有较高的强度、硬度和较好的塑性、韧性,通常要经过调质处理(淬火后高温回火)后使用,因此也叫调质钢,主要用于制造受力较大的机器零件(如轴、齿轮、连杆等);

30-55 steel belongs to medium carbon steel, with high strength, hardness, good plasticity and toughness. It is usually used after quenching and tempering (high temperature tempering after quenching), so it is also called quenched and tempered steel. It is mainly used to manufacture machine parts (such as shaft, gear, connecting rod, etc.) with greater stress;

60钢及碳的质量分数更高的钢属高碳钢,具有更高的强度、硬度及耐磨性,且其弹性很好,但塑性、韧性、焊接胜能及切削加工性能均较差,主要用于制造要求较高强度、耐磨性及弹性的零件(如钢丝绳、弹簧、工具)。

60 steel and steel with higher carbon content belong to high carbon steel, with higher strength, hardness and wear resistance, and good elasticity, but poor plasticity, toughness, welding ability and machining performance. It is mainly used for manufacturing parts requiring higher strength, wear resistance and elasticity (such as wire rope, spring and tools).

双杨较高的优质耐磨板,其性能和用途与相同较低的钢基本相同,但其淬透性稍好,可用于制造截面尺寸稍大或对强度要求稍高的零件。

The high-quality wear-resistant plate with double Aspen has the same properties and uses as the same lower steel, but its hardenability is slightly better. It can be used to manufacture parts with larger section size or higher strength requirements.
