20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. , 20 # material has low strength, good toughness, plasticity and good weldability Chemical composition of 20 # round steel bar: C: 017 ~ 023, Si: 017 ~ 037, Mn: 035 ~ 065, S: ≤0035, P: ≤0035, Cr: ≤025, Ni: ≤030, Cu: ≤025 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min 25%,SPA-H chemistry.

The weldability of SPA-H chemistry is good. It means that under certain process and construction conditions, can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

The company strengthens process management and pays attention to assessment One of the key points of good service is to strengthen the process management and improve the evaluation mechanism Make the after-sales service system more perfect and provide better service for customers,SPA-H chemistry.
