PVQ P355NL2 boiler steel plate,Medium thick steel plate refers to the steel plate with a thickness of not less than 3 mm but less than 20 mm. It can be produced by reversible hot rolling medium and heavy plate mill, and its thin products can also be processed by cold rolling mill. , Medium thick steel plates are mainly used in boilers, shipbuilding, railway cars, automobiles, containers, military industry, national defense, construction, bridges and containers.
PVQ P355NL2 boiler steel plate,45# steel is commonly used medium carbon quenched and tempered structural steel. The steel is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained 45# steel normalizing can improve the cutting performance of roughness less than 160HBS,PVQ P355NL2 boiler steel plate.
Rolling of steel plates is the core of the entire steel rolling production process The billet is deformed by rolling The rolling process plays a decisive role in product quality The quality requirements of rolled products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish Finishing: It is the last process in the rolling process, and it is also a more complicated process It plays a final role in guaranteeing the quality of the product,PVQ P355NL2 boiler steel plate.
PVQ P355NL2 boiler steel plate,20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel It has low strength, good toughness, plasticity and good weldability Chemical composition of 20 # round steel bar: C: 017 ~ 023, Si: 017 ~ 037, Mn: 035 ~ 065, S: ≤0035, P: ≤0035, Cr: ≤025, Ni: ≤030, Cu: ≤025 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min 25%,PVQ P355NL2 boiler steel plate.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
