4140 steel plate supplier – 4140 Plates Rolled, Annealed, and Pre-Hard | OTAI
What is 4140 steel
4140 steel is a cold drawn annealed steel of relatively high hardenability with its chromium content providing good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength.
4140 alloy steel well to heat-treatment and is relatively easy to machine in the annealed condition. 4140 steel has good strength and wear resistance, excellent toughness, coupled with good ductility, and the ability to resist stress at elevated temperatures. (4140 flats steel)
One of our customers Nick from the Argentina sent us an inquiry for 4140 steel plate. After giving him a quote, he gave us feedback that our price is more expensive than others. We sent him the MTC to prove it was the real 4140. And suggested he compare whether the MTC of low-priced is the real 4140 or not. (4140 steel plate supplier)
