ST37.4 Pipe and DIN 1630 ST 37.4 NBK Seamless Hydraulic Tubes supplier

DIN 1630 ST 37.4 NBK Seamless Hydraulic Tubes supplier in India

ST37.4 Pipe

ST37.4 Pipe distributors and exporters in India

The ST37.4 Pipe is a low-carbon steel tube that is available at a low cost. The alloy of the Hydraulic Steel Tubes ST37.4 is made with a maximum of 0.17% carbon and 0.35% manganese. Due to the chemical formation of the St37.4 Pipe, these are easily weldable and have high ductility. We manufacture DIN 1630 Grade St 37-4 Carbon Steel Seamless Tubes in our factory following the DIN specifications and other national and international standards. However, remember that the low carbon content in DIN 1630 St37.4 Seamless Carbon Steel Pipe is not as hard as the high carbon steel pipe. However, we can perform carburizing on these pipes to increase their surface hardness.

The DIN 1630 St37.4 Tube covers the non-alloy steel seamless tubes that have a high-quality requirement. We are one of India's top manufacturers and suppliers of DIN2391 St37.4 NBK Seamless cold drawn tubes. We offer full customization in terms of their shape, size, and dimensions. These pipes are available in different forms such as square, rectangle, circular, etc., and each has varied uses across industries.

Our EN10305 ST37.4 Seamless Tubes are robust in construction and are very durable. We use the latest technologies while manufacturing the DIN 2391 ST 37.4 Tube to ensure high performance and less maintenance. We can also customize the surface treatment of their pipes as specified by our clients. This helps to keep our products protected from various reactions and improves their overall longevity.
