How to prevent api 5l grade b equivalent cutting cracks

Standard:API 5L PSL1|PSL2.
Scope:API 5L is generally refers to the standards of pipeline steel, include pipeline pipe and pipeline steel plate.
API 5L line pipe steel grade levels:GR. B, X42, X46 and X52, X56, X60, X70 and X80.
Details

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 api 5l grade b equivalent.

Our ogistics department has a professioanl team to support the goods’ transportation and delivery time. Its responsibilities: make customs clearance documents, track products production process, and update shipping information for customers. The company will adhere to the mission of reflecting social values, take the scientific management system as the guarantee of daily operations, and provide continuous technological innovation to support its sustainable development.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This api 5l grade b equivalent production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate api 5l grade b equivalent size.
