1.4372 stainless seamless pipe

1.4372 stainless steel has certain acid and alkali resistance, high density, no bubbles, no pinholes when polished, etc. It is a high-quality material for the production of various watch cases, watch strap bottom covers, etc. Mainly used to make decorative pipes, industrial pipes, and some shallow stretched products.

200 series stainless steel was first successfully developed in the United States as a substitute for 300 series stainless steel during World War II. At that time, due to the war, nickel, as a strategic material, was strictly controlled by relevant countries, and the supply of nickel in the United States was seriously insufficient. In order to solve the production and supply problems of stainless steel when the supply of nickel is seriously insufficient, the United States has developed this new series of austenitic stainless steel grades using manganese instead of nickel.

After the end of World War II, the supply of nickel in the United States gradually improved. Therefore, the production of 300 series stainless steel was no longer restricted by the shortage of raw materials, so the 200 series did not receive major development. Several Indians who participated in the development of 200 series stainless steel originally brought the 200 series stainless steel varieties developed in the United States back to India after returning to India, considering that India is a country with relatively rich manganese resources and a lack of nickel resources.
