What is the difference between 16mo3 steel high strength and ordinary strength steel

Low temperature SA662 pressure vessel plate, 16Mo3 steel high strength heat treatment:All grade A SA662 steel plates and SA662 grade B and C steel plates with thickness greater than 40mm shall be normalized.SA662 grade B and C steel plates up to and including 40mm in thickness are usually supplied in rolled condition. It can also be supplied with normalizing stress relief treatment or normalizing + stress relief treatment.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for 16mo3 steel high strength.

Compared with thick steel plates, 16mo3 steel high strength, thin steel plates have many obvious advantages in steel plate processing and use. It is precisely these advantages of thin steel plates that make them more and more popular in various industries. First, compared to those thicker steel plate materials, thin steel plates are generally thinner in thickness. Thin steel plates themselves are lighter and thinner, and their weight is lighter, which is very convenient for handling during construction and transportation. It can save some storage and transportation space.
