S355N is a kind of weldable fine grain structural steel grade under EN10025-3 standard. It is often delivered in normalized or normalized rolled condition. There are various shapes available for ASTM A709 high strength steel, S355N: steel plates, strip and steel sections. When producing this steel S355N plates, dimension, tolerances on thickness, width, length and shape shall be in accordance with the requirement given in the order by reference to the relevant documents according to EN10025-1 standard.
42CrMo alloy steel ASTM A709 high strength steel: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.
The clad steel plate is based on carbon structural steel, which is sprayed with stainless acid resistant and heat-resistant steel on the surface. The clad steel plate is widely used to make acid and alkali resistant container. Advantages of clad steel plate: The appearance of the clad steel plate is very smooth, the quality is very good, and it will not rust. Disadvantages of clad steel plate: the ASTM A709 high strength steel, clad steel plate has better requirements for production technology and are more expensive.
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to ASTM A709 high strength steel customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.
