SPA-H curtain wall steel sheet datasheet and standard

Abrasion resistant steel SPA-H curtain wall steel sheet which is also known as (AR steel) wear resistant steel, is developed to have longer service life than mild steel. Abrasion resistant steel is widely used in underground mines, cement industry, road construction, mining and open-pit mining and metallurgical industries and manufacturing other wear-resistant parts.

Non-destructive flaw detection of steel plates is a test method for inspecting the SPA-H curtain wall steel sheet surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used SPA-H curtain wall steel sheet steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

The common delivery status of SPA-H curtain wall steel sheet, SA516 Gr 70 plate is as follows:
1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point.
2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air).
3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly.
4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.
