The heat treatment effect the surface of ASME SA213 T9 steel pipe


After the ASME SA213 T9 steel pipe was treated with different heat treatment process, different metallographic structure could be obtained, and the surface roughness of ASME SA213 T9 steel pipe was different after mechanical processing.

The surface roughness of ASME SA213 T9 steel pipe is related to its internal structure. The microstructure obtained from the five thermal treatment processes is basically two-phase, in which ferrite is matrix phase and plastic phase, and granular cementite is second phase and brittle phase.

The surface roughness of ASME SA213 T9 steel pipe depends on the surface roughness of cementite and ferrite swept by blade. The surface roughness of ASME SA213 T9 steel pipe is mainly determined by the surface roughness of matrix ferrite because the number of second phase granular cementite is much less than that of matrix ferrite.

After normalizing, annealing, spheroidizing annealing, quenching medium temperature tempering and normalizing high temperature tempering, ASME SA213 T9 steel pipe can be machined to obtain different surface roughness.

Market status of ASME SA213 T5 boiler pipe this week With the need of the policy, the market status of ASME SA213 T5 boiler pipe  is changing. Katalor as a professional steel supplier and exporter in China. We produce  ASME SA213 T5 boiler pipe with good quality and best service. Now Katalor will analyze the market of  ASME SA213 T5 boiler pipe  for you. This week's ASME SA213 T5 boiler pipe markept continued to remain strong, but in the strong environment of the operation, it gradually showed the characteristics of the off-season. With the arrival of the wheat harvest season, the impact of high temperature and rainy weather gradually increased, the overall inventory decline rate slowed down significantly. ASME SA213 T5 boiler pipe  inventories fell by 360,000 tons this week, which has narrowed for two consecutive weeks, down 100,000 tons from last week, down 250,000 tons from last week, down 100,000 tons fro...
