equivalent grades of nm450 steel material heat treatment

Our company is a large equivalent grades of NM450 steel steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special equivalent grades of NM450 steel steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.

For S420NL weldable fine grain structural steel plate, it is produced under specification EN 10025-3. The yield strength of S420NL plate shall be above 420Mpa for the thickness below 16 millimeter, 400MPa min. for thickness below 40mm, 390MPa min. for thickness below 63mm. The tensile strength for thickness below 100mm of this steel grade S420NL shall be within 520-680Mpa. For the Mill test certificates of steel S420NL,equivalent grades of NM450 steel, our mill would like to issue format according to EN 10204 3.1.

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel equivalent grades of NM450 steel is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.

The purpose of equivalent grades of NM450 steel quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of equivalent grades of NM450 steel. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

A387 Gr 91 Cl 1 alloy steel is an option for use in sour service environments. The material has good weldability and with its heat resistant qualities, the material is a highly versatile steel which can be used in numerous applications. A387 Gr 91 Cl 1 steel tensile requirementsTensile strength, ksi [MPA]: 85 to 110 [585 to 760]Yield strength, min, ksi [MPa]/(0.2% offset): 60 [415]Elongation in 2 in. [50mm], min, %: 18
