Alloy Steel Seamless Tube DIN 17175 15Mo3, 13CrMo44, 12CrMo195
Alloy steel tubes is a kind of steel alloyed tube with other elements in amounts
of between 1 and 50% by weight to improve its mechanical
properties.Alloying
elements are added to achieve certain properties in the material.
As a guideline,
alloying elements are added in lower percentages (less than 5%) to
increase
strength or harden ability or in larger percentages (over 5%) to
achieve special
properties, such as corrosion resistance or extreme temperature
stability.
