4130 alloy steel sheets offer good weldability without compromising steel abrasion and impact resistance and be made even stronger throough heat treatment. They are typically used in structural applications, including gears, fasteners, and and aircraft exteriors. 4130 alloy steel sheets are offered as NORMALIZED (NRZ) or ANNEALED (ANL) in different thicknesses and dimensions in inches. Annealed steel sheets are "softer" than their normalized steel counterparts and offer higher workability. They meet AMS 6350 Standard. Normalized steel sheets offer a higher strength tolerance.
