BBN GroupMay 15, 2020· The surface hardness of NM400 steel products usually reaches 360 450 HB. NM400 wear resistant steel is used for processing and manufacturing of wear resistant wearing parts for mining and various construction machinery.NM400 wear/ abrasion resistant steel plate with improved Nm400 goes beyond wear resistance, allowing you to protect your equipment investment and work more effectively. In truck bodies and containers, NM400 ensures a longer lifetime and highly predictable performance. Its high strength and hardness often allows for a thinner plate, enabling a higher payload and better fuel economy.

For instance, a soft Rockwell value is 45, whereas a hard value is 60. What Does a High RC Rating Mean? A high Rockwell C rating means the tested steel is high strength. Any value ranging in the mid 50s and above on the Rockwell C scale is considered hard.

Slight variations in chemistry are present depending on the steel producing mill and these wear resistant steel plates offer excellent resistance against

Points for attention in NM400 steel plate cutting steel

NM400 steel plate is a kind of wear resistant steel plate. NM The first letter of the Chinese phonetic alphabet, and 400 is for wear resistance. Wear resistance is the Brinell hardness HB value, and the hardness value of domestic NM400 steel plate is 360 420.NM400 High strength Abrasion resistance platesWith high speed development of technology and modern industry,manufactures are more likely to use high strength abrasion resistance steel plates so as to reduce the economic lost brought by part wear.NM400 under GB/T24186 are mainly used for charging cranes,excavators,dumpers,conveyers,trucks,breaking and cutting tools,waste disposal and recovery China Nm400 HRC 400 Wear/Abrasion Resistant Steel Plate China Nm400 HRC 400 Wear/Abrasion Resistant Steel Plate, Find details about China Wear Resistant Steel Plate, Abrasion Resistant Steel Plate from Nm400 HRC 400 Wear/Abrasion Resistant Steel Plate Qingdao Hart Industrial Technology Co., Ltd.

Cutting of Wear Resistant Steel Plate NM400

NM400 Steel Plate Property AnalyzeNM400 wear resistant steel plate is a kind of heat treated steel plate. Like most wear resistant steel plates on the market, it is heated to a certain temperature. When the temperature is above 300 degrees, the hardness will drop rapidly.List of Hardness Values of Blocks MCreatorList of Hardness Values of Blocks. Section. Data lists.

Hardness of Water USGS

Oct 22, 2019· Hardness is caused by compounds of calcium and magnesium, and by a variety of other metals. General guidelines for classification of waters are0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.Hardness test tec scienceHardness values obtained with different process variants cannot be compared with each other. In addition, the hardness value obtained with a certain process method must lie within a certain range. For values outside this range, the method should be changed because the indenter has either penetrated too strongly or too weakly into the material.China Nm400 Nm500 Wear Resistant Steel Plate Cutting Wear resistant steel plate with hardness 400HB 650HB NM400 NM500 wear steel plate ApplicationCrusher,sieve plate,feeding hopper,blade plate,conveyor,bucket,cutting edge,dump truck,scraper,industrial truck,railway wagon,bulldozer,excavator,screw conveyor and etc. wear resistant steel plate NM400 property
