nm500 gb standard sheet standard pdf

ASTM A387 steel plate is suitable for temperature range (316-593). It's high temperature performance is still the focus of attention, even if the current trend is for applications with high CVN toughness requirements. ASTM A387 steel NM500 gb standard sheet tends to be fin-shaped, low-silicon, low-sulfur, calcium treatment, and occasionally produced Q&T to provide the highest level of toughness.

Our company was founded in 2000, which initially committed to providing high-quality steel NM500 gb standard sheet products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export NM500 gb standard sheet steel to the international market, opening up the international steel market.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the NM500 gb standard sheet metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between NM500 gb standard sheet strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

The basic principle of NM500 gb standard sheet, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

Both parties shall confirm the NM500 gb standard sheet material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the NM500 gb standard sheet steel plant.
