10crmo910 pipe eqivalent material

Delivery status of 10CrMo910 pipe, 13CrMo4-5 steel plate: normalizing + tempering, quenching and tempering. If the 13CrMo4-5 plate thickness is less than 100mm, it is normalized + tempered; if the thickness is 100mm-150mm, it is normalized + tempered or quenched + tempered; if the thickness is 150mm-250mm, it is quenched + tempered. Different delivery status can be selected according to the demand, and flaw detection standard requirements, flaw detection grade requirements, Z-direction performance requirements, requirements for adding special alloy elements, etc. can also be added, but they need to be communicated between the supplier and the demander and indicated in the contract.

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 10CrMo910 pipe.

The weldability of 10CrMo910 pipe is good. It means that under certain process and construction conditions, 10CrMo910 pipe can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
