Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
SKD12 features and applications: SKD12 is suitable for various hardware cold punching dies, and large and complex punching dies that can withstand greater impact.SKD12 characteristics: 1. Air quenching die steel has deep air quenching hardening performance; 2. High wear resistance, micro deformation, high hardenability, high compressive strength; 3. Carbide distribution is more uniform than Cr12 steel.
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”)
After quenching and tempering, 40Cr alloy steel plate and A514 Gr R alloy steel plate sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A514 Gr R alloy steel plate is good. It can be hardened to Ф28 ~ 60mm during water quenching and Ф15 ~ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ~ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
