What is the difference between 4130 and 4140 steel?
What is the difference between 4130 and 4140 steel?
4130 contains 0.28-0.33% Carbon and 0.40-0.60% Manganese, while 4140 contains 0.75-1.00% Manganese and 0.38-0.43% Carbon. – 4140 alloy steel has greater hardenability and strength than 4130. – 4130 steel is easier welding than AISI 4140 steel and its wear-resistant performance is lower than in 4140.Sep 15, 2020
4140 steel plate has high fatigue strength, excellent toughness, and good corrosion resistance. ... This material is often used for shafts, crankshafts, gears, collars, and machinery parts because of its toughness, abrasion and impact resistance, and high fatigue strength.
