Q235NH and Q295NH material introduction

Q235NH, "Q" means the letter of yield pinyin, "235" means the yield strength is 235MPa, "NH" is the letter of weather resistance.

Q235NH full name: atmospheric corrosion-resistant hot continuous rolled steel, also known as Corten steel, corrosion-resistant steel.

Widely used in: containers, power plant chimneys, railway engineering and other outdoor steels, such as large-scale outdoor sculpture steel, weathering steel (ie, atmospheric corrosion-resistant steel) is a low-cost and high-quality low-alloy steel series between ordinary steel and stainless steel.
