09CuPCrNi-A weathering steel machinability

The ability to resist plastic deformation and fracture under the action of external load is called 09CuPCrNi-A weathering steel strength, and the local resistance of solid materials to external objects such as indentation and scribing is hardness. In the mechanical properties of weathering steel, strength and hardness are related indexes, while plasticity (elongation, reduction of area) and toughness (impact value) are related indexes.

Recently, a symposium on the celebration of the 70th anniversary of the founding of the People's Republic of China by the iron and steel industry was held in Beijing Convention Center. The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, BBN 09CuPCrNi-A weathering steel Steel Staff sang songs to the mark the 70th victory anniversary. In the last of September, Henan BBN Steel organized all employees to sing ""My Country and I"" and made a film.

Due to the rapid development of the epidemic globally, many nations have moved to a position of “social distancing” in an effort to delay the spread of the COVID-19 virus. Cases have now been detected in most countries worldwide and community spread is being detected in a growing number of countries. The World Steel Association (worldsteel) has cancelled or postponed all our upcoming membership committee meetings. In a few cases they may go ahead electronically but the majority will be reconvened at a later date.

The mechanical properties of 09CuPCrNi-A weathering steel steel plate are related to elastic or inelastic reaction or related to stress-strain relationship. Tensile strength, yield point, elongation and impact absorption energy are the main indexes to express the mechanical properties of hot rolled steel plate. Its value represents the ability of steel 09CuPCrNi-A weathering steel to resist various actions, which is the main criterion to evaluate the quality of steel material, and also the main basis for material selection and strength calculation in steel plate design.
