Common quality problems of CNC 19Mn6 pressure vessel steel sheet cutting

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials 19Mn6 pressure vessel steel sheet. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

The strength indexes of 19Mn6 pressure vessel steel sheet pipeline steel mainly include tensile strength and yield strength. At the same time, the yield strength ratio (yield strength to tensile strength ratio) of pipeline steel is also required, which is generally in the range of 0.85-0.93. Pipeline steel shall have enough high impact toughness (crack initiation and crack arrest toughness). For the base metal, when the toughness of the 19Mn6 pressure vessel steel sheet material meets the requirements of crack arrest, its toughness generally can also meet the requirements of crack prevention.

Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and 19Mn6 pressure vessel steel sheet steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and 19Mn6 pressure vessel steel sheet medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.

S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. 19Mn6 pressure vessel steel sheet, S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate, 19Mn6 pressure vessel steel sheet.

Our company's logistics breaks through the perspective that the center of transportation service is ability, and emphasizes that the purpose of transportation service is customer first. Customer demand determines the content and mode of transportation service, while production is often small batch, diversified and consumer demand tends to be diversified.
