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 A573 welding structural steel tends to be fin-shaped, low-silicon, low-sulfur, calcium treatment, and occasionally produced Q&T to provide the highest level of toughness.
We cooperated with the Peruvian government for many years. And supply them large diameter steel pipes and pipe fittings to support their Hydropower Station Projects. We do 100% UT, RT, Hydraulic test and so on tests for the ASTM A573 welding structural steel steel pipes. And do PT, MT and so on tests for the pipe fittings. We published "Welding Procedure Qualification report" after production. And our mill will keep the test record in the documentary department for 5 years. If meet any problems in following application, we can check the test record easily and assist to solve problems at the first time.
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.
Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export ASTM A573 welding structural steel to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
