What is the effect of S355NL and S355ML surface treatment on its properties

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep S355NL and S355ML processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and S355NL and S355ML steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

Flat S355NL and S355ML steel plate, with a small thickness of the plate. Low carbon equivalent, to adapt to automatic submerged arc welding, plasma welding and other S355NL and S355ML welding process requirements.

The thickness of cold-rolled steel sheets is generally relatively small, and the thickness of hot-rolled plates can be larger. The surface quality, appearance, and dimensional accuracy of cold-rolled steel sheets are better than those of hot-rolled plates, and the thickness of cold-rolled steel sheets can be rolled as thin as about 0.18mm. S355NL and S355ML, Hot-rolled plates has high strength, good toughness, easy processing and good weldability and other excellent properties.

What is S355NL and S355ML, boiler steel consumption rate? The cost of the boiler, to a large extent, depends on the steel consumption of the boiler. The so-called boiler steel consumption rate refers to the tons of boiler steel used per 1t / h evaporation capacity of the boiler, also known as the boiler steel consumption per unit evaporation. The boiler steel consumption rate of boilers with different parameters, capacities and structures is different.

Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. S355NL and S355ML, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products S355NL and S355ML are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
