A573 Gr.70 steel and A517 Grade A steel comparison

Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of A573 Gr.70 steel and A517 Grade A steel comparison and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.

Alloying elements can strengthen the properties of structural steels. A573 Gr.70 steel and A517 Grade A steel comparison, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.

Laser cutting, it is a specific way of cutting A573 Gr.70 steel and A517 Grade A steel comparison steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting A573 Gr.70 steel and A517 Grade A steel comparison speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.
