What is Q345D carbon steel plate sheet machinability

This is the second year we have been golden supplier on Alibaba. Over the decades, we have accumunited rich customer resources and have established stable copperation with many customers all over the world. So we did not reply on Q345D carbon steel plate sheet B2B platforms. But with the development of the company and the increasing of the company reputation, it is necessery for us to open up more channels for customers to reach us.

In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.

ASME SA203 is a low-nickel alloy steel, including five grades of A, B, D, E, and F. SA203 Gr.E steel plate impact temperature -101 ° C. SA203 Gr.D / E / F has good impact toughness and mechanical properties under low temperature working conditions, and is usually used in low temperature environments of -70 ～ -101 ℃ (the tempered state can be -107 ℃). Q345D carbon steel plate sheet Smelting method: It is smelted by electric furnace + refining outside the furnace + vacuum degassing, and should be fine grain killed steel.

For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The Q345D carbon steel plate sheet, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.

We exported 2150 Tons SG295 steel coils to Sudan. The Sudan customer is LPG cylinder manufacturer. Before our cooperation, he usually purchased SG295 steel coils from UAE and Turkey. And he got to know our company through our regular customers in Uganda, UAE, and his friends in China. Then he gave us the order. We invited the customer to visit us before contract, but he insisted to visit us when the Q345D carbon steel plate sheet goods are finished production. After inspecting the size, package in workshop and witness the lab test for the SG295 steel coils, the customer was very satisfied to our quality control and professional arrangement.

Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to Q345D carbon steel plate sheet 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.
