High-strength steel plate WEL-TEN for the structural parts of construction machinery attachments.
WEL-TEN Series, Nippon Steel Brand
Clamp, pull, break. For the high-strength enhancement of arms and frames that bear large loads.
Grapples, forks, crushers, and demolition attachments repeatedly perform actions such as clamping, pulling, bending, and breaking objects. Structural components like arms, frames, and brackets require strength and toughness to withstand large loads. For components where you want to maintain structural strength while minimizing weight increase, we recommend high-tensile steel plate "WEL-TEN." WEL-TEN is a steel plate suitable for enhancing the strength and reducing the weight of welded structural components subjected to tensile and bending loads. It is used in arms, side plates, frames, and mounting parts, and it is important to select materials according to the cause of damage, such as combining wear-resistant steel plate ABREX in areas that come into direct contact with cutting edges or objects. At Kumagai Special Steel, you can consistently consult us from cutting to machining, bending, and welding, even for drawings that include composite materials.
