PRODUCT DETAILS

Product Details

Chromium molybdenum alloy steel pipe has high tensile strength, corrosion resistance and high temperature strength，Chromium-molybdenum steel pipe has a better strength-to-weight ratio than other steels, which allows us to use thinner wall pipe or smaller diameter pipe to reduce overall weight. Chromium molybdenum tube, also known as alloy tube。Chromium molybdenum steel is an alloy of chromium (Cr), molybdenum (Mo), iron (Fe), and carbon (C). Chromium-molybdenum steel, also known as medium-temperature hydrogen-resistant steel, refers to the steel type that adds Cr (<10%), Mo and other alloying elements to significantly improve the high-temperature strength limit and creep limit, and has good hydrogen corrosion resistance and high temperature resistance. Therefore, it is widely used in hydrogen-containing devices and high-temperature equipment such as oil refining and chemical industry. It is one of the commonly used steel types for pressure vessels.
