Structural steel alloy steel plates are unaffected by high temperatures due to their Molybdenum content, creating rock-like bodies. Combustible industries involve high-temperature procedures, where assemblies made from cheap steel can wither away. Alloy steel sheets NM400 material specification are robust, recyclable, and have enhanced surface quality. A balance between both Steel and chromium forms DIN 15 Mo3 Alloy Steel plates imperious to oxidation and erosion, with brittle-free hardenability from Steel and Chromium. They don't age or decay, are anti-corrosion and have excellent thermal and heat conductivity.

The final heat treatment of quenched and tempered alloy steel, NM400 material specification is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. NM400 material specification, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
