What is SA516Gr70N-Z15? SA516Gr70N-Z15 American Standard Container Steel Plate Regular Rolling

SA516GR70 belongs to the medium and low temperature pressure vessel steel plate, the implementation of ASME standards, the N in sa516gr70N represents the meaning of normalizing, normalizing on the basis of hot rolling, heat treatment to improve the toughness of steel, as the final heat treatment (1) can refine austenite grains and homogenize the structure. (2) Reduce the ferrite content in the sub-eutectic steel, so that the pearlite content is increased and refined, so as to improve the strength, hardness and toughness of the steel.

Dancing steel to the sun

Z15 is directional performance, and the suffix with Z15, Z25, Z35, sa516gr70N-Z15, sa516gr70N-Z25, sa516gr70N-Z35 is required to require the corresponding Z-directional performance, and this kind of steel is also Z-oriented steel.

SA516Gr70N Chemical Composition:

SA516Gr70 steel plate carbon content C: ≤0.31

The silicon content of SA516Gr70 steel plate Si: 0.13-0.45

Manganese content of SA516Gr70 steel plate Mn: 0.79-1.30

Phosphorus content of SA516Gr70 steel plate P: ≤0.035

SA516Gr70 steel plate sulfur content S: ≤0.035

SA516Gr70's main products are steel plates for building structures, bridge plates, steel plates for hydropower and nuclear power, steel plates for petrochemical and coal chemicals, boilers and pressure vessel steel plates, steel plates for marine engineering equipment and shipbuilding, and the Z-direction performance of the steel plate is the performance of the steel plate thickness direction, and it is also the steel plate anti-layered tear test, which is often used in the thickness direction of the steel plate to try to add a very vibration stress part, the Z-direction performance steel plate is suitable for 16mm-300mm thick steel plate, and the Z-direction performance test has extremely strict requirements for the sulfur S content of harmful elements of the steel plate. The steel plate is tested in accordance with the European ultrasonic flaw detection standard to ensure that there are no defects, interlayers, bubbles, inclusions, cracks, etc.
