What is SCM420?
What is SCM420?
SCM420 are alloy steel with high hardenability, temper brittleness, well weldability, less cold cracking tendency, good machinability, and great cold plastic strain. SCM420 generally are used for the parts which need high wear resistance, such as gears, shafts, high-pressure pipes, all kinds of fasteners, and so on.
What is SCM440?
SCM440 is medium carbon chromium molybdenum alloy steel, which is an alloy steel containing chromium and molybdenum. The chromium content of the alloy provides good hardness permeability, and the molybdenum element imparts average hardness and high strength.
Is 8620 a chemical composition?

What type of steel is 16MnCr5?
alloy steel
Steel grade 16MnCr5 is a structural steel for parts that are surface hardened. It is made in accordance with the BS EN ISO 683-3 standard (formerly EN 10084). Classification: Special alloy steel.
What is SCM steel?
Steel Composite Material (SCM) sheet is made of two external steel skins thermally bonded to a low-density polyethylene (LDPE) core. Combined, these materials form a structure that is extremely strong and energy absorbent – providing durability, impact resistance and aesthetics for the most demanding applications.
What is 20CrMo?
20CrMo Alloy Steel GB 20CrMo steel is a kind of Chinese alloy steel for engineering and mechanical structure purpose, which is generally used in quenching or tempering or carburizing and quenching.
What is 42CrMo?
42CrMo (American grade: AISI 4140) is one of the representative medium carbon and low alloy steel. Due to its good balance of strength, toughness, and wear resistance, 42CrMo high-strength steel is widely used for many general purpose parts including automotive crankshaft, rams, spindles, crow bars, and ring gears.
What is the Rockwell hardness of 4140 steel?
4140 (modified) Cold Finished, Annealed Alloy Bar Stock Typical hardness is Rockwell “C” 19/24. Typical tensile strength 114,000 PSI.
Is 8620 a high carbon steel?
A medium-strength, low-carbon alloy steel, 8620 contains good toughness and strength properties, along with good core strength.
What is the alloy content of 8620?
Alloy 8620 steel is a low-carbon carburizing/case-hardening steel that contains nickel, chromium, and molybdenum as alloying elements. The nickel content provides 8620 with good ductility and toughness while the chromium and molybdenum in its composition increase its hardness penetration and wear.
What is 20MnCr5 material?
20MnCr5 steel is a low alloyed engineering case hardening steel for parts which require core tensile strength of 1000 – 1300 N/mm² and good wearing resistance. It is used in boxes, piston bolts, spindles, camshafts, gears, shafts and other mechanical controlling parts.
What is ASTM A29?
ASTM A29 4118 steel is one popular alloy steel used as engineering steel. There are steel equivalent of aisi 4118 steel, like JIS SCM420, DIN 18CrMo4 steel or 1.7243 steel.
