high strength hardness

Microstructure and hardness properties of butt and fillet

High-strength steel HY-80 is widely used for ship and submarine construction This steel has a good combination of strength ductility and toughness at room temperature and sub-zero temperatures Fusion welding is a very important process in high-strength steels but the welding problem appears in a heat affected zone (HAZ) near the fusion line where a coarse grain heat affected zone (CGHAZ

Influence of carbon on hardness and strength of steels

The strength of the steel is therefore decisively determined by the lamellar cementite structure The finer the pearlite microstructure the higher the strength A very fine lamellar structure can be achieved by increased undercooling It should be noted however that as the cooling rate increases no thermodynamic equilibrium can ultimately be established between or within the phases Both

What is Total Hardness?

High total hardness can result in abnormal cloudiness and the formation of scale However levels of hardness that are too low could make the water corrosive and more aggressive Thus industries that utilize equipment and machinery that handle water should ensure that the total hardness levels are maintained at appropriate levels to prevent the water from becoming corrosive
