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 ASTM A588 high strength steel tends to be fin-shaped, low-silicon, low-sulfur, calcium treatment, and occasionally produced Q&T to provide the highest level of toughness.
Our company's ASTM A588 high strength steel power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the ASTM A588 high strength steel utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
Try to use ASTM A588 high strength steel high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the ASTM A588 high strength steel temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for ASTM A588 high strength steel.
In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel ASTM A588 high strength steel products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
