JIS Smn420, Smn438, SCR420, SCR440 Cold Carbon Alloy Structural Steel Round Bars
JIMISTEEL in the business of Tool steel / Mold steel / Die steel / Alloy steel, etc. The main product has Plastic mold steel(P20 /1.2083 / NAK80 / 1.2312 / 1.2316.); Hot Work steel (H13 / 1.2344 / FDAC / SKD61.); Cold work steel (O1 / Cr12 / Cr12Mov / SKD11 / M2 / T1); Carbon steel (Q235 / S45C / S50C / ) (4140 / SCM440)
1.Base Parameter
2.Heat Treatment Process
Heat treatment specification: quenching: 880 ºC for the first time, 780 ~ 820 ºC for the second time, water cooling and oil cooling; Tempering 200 ºC, water cooling, air cooling.
3.Application
The strength and hardenability of SCr420 alloy structural steel are higher than that of 15Cr steel, but the toughness is poor; It has good weldability and does not need heat treatment after welding. SCr420 is used for carburized parts with high central strength and surface wear, large size, or complex shape but low load, such as gears, gear shafts, cams, piston pins, worms, etc. SCr420 can also be used as quenching and tempering parts with high working speed and medium impact load
.Our Service
A. Steel plates: Cutting by bandsaw machine, milling, heat treatment, etc
B. Round bars: Cutting by bandsaw machine, peeling, grinding and turned, heat treatment, etc
C. Ultrasonic testing and hardness testing
