Common quality problems of CNC JIS SM490B plates cutting

The technology center has always been focusing on application research, improving market realization and scientific and technological contribution rate; taking user demand as the goal, highlighting the personalized development of products; taking the joint development of industry, University and research, and technology integration as the means, improving the starting point and level of innovation, and realizing the breakthrough of core technology; taking advanced research as the guide, pursuing the leap of technological development; taking system and mechanism innovation as the driving force, Promote and realize the working concept of technological innovation.

ASTM A387 steel plate is suitable for temperature range (316-593). It's high temperature performance is still the focus of attention, even if the current trend is for applications with high CVN toughness requirements. ASTM A387 steel JIS SM490B plates tends to be fin-shaped, low-silicon, low-sulfur, calcium treatment, and occasionally produced Q&T to provide the highest level of toughness.

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with JIS SM490B plates, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.

Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled JIS SM490B plates plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy JIS SM490B plates steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.
