Large stock nm500 steel equivalent grades from China factory

The material used for the elbow is carbon structural steel or high-quality carbon structural steel 20#. These two materials can not only ensure that the carbon steel elbow has good hardness, strength and wear resistance, but also ensure the plasticity of the elbow, and ensure that the elbow will not be broken or wounded due to stress during forming. However, cast steel elbows are also used in some special piping systems. This type of piping system requires high mechanical properties of the elbow, and it is difficult to form by forging and other methods in the process.

Semi-endless rolling technology has three advantages: the NM500 steel equivalent grades product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and NM500 steel equivalent grades pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
