Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;
According to the different manufacturing processes, there are hot rolled steel pipes and cold drawn hot rolled HARDOX 400 sheet seamless steel pipes. BBN sells seamless pipes of different sizes, weights and grades. Customers can choose between black hot rolled HARDOX 400 sheet line pipes and galvanized line pipes. From 2-3/8" to 24", steel grade A, B, X42, X80.
Mechanical Properties A242 steel:ASTM A242 specification is made for low alloy steel with high strength, it has good atmospheric corrosion resistance, some applications has shown that it has better corrosion resistance than ASTM A36 steel and ASTM A572 Grade 50.Tensile: 70 ksi min (3/4 and under), 67 ksi min (3/4-1.5) 63 ksi min (over 1.5-4)Yield: 50 ksi min (3/4 and under), 46 ksi min (3/4-1.5) 42 ksi min (over 1.5-4)Elongation: 16% min in 8” 19% min in 2” (for plates wider than 24”)
The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The hot rolled HARDOX 400 sheet, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.
