concrete reinforcing bar (rebar)
In the United States, the size designations of these (usually) mild steel bars used to reinforce concrete are set by ASTM International.¹ Distributors usually stock rebar in 20- and 60-foot lengths. Besides mild steel, rebar is also made in stainless steel (cost-effective, for example, for concrete bridges where salt is spread on winter ice) and other specialty alloys. Almost all bars are deformed, that is, a pattern is rolled onto them which helps the concrete get a grip on the bar. The exact patterns are not spSee more on sizes chemistry of 400b grade Bending

Nevertheless, this is still not low enough to create the large concentration of vacancies needed for the band bending.See all results for this questionWhat is 400 steel?The 400 series of stainless steels have a higher carbon content, giving it a martensitic crystalline structure that provides the end product with high-strength and high-wear resistance. The 400 series steels tend to be used in agricultural equipment, gas turbine exhaust silencers, hardware, motor shafts, and more.See all results for this question

Since the K-Factor is based on the property of the metal and its thickness there is no simple way to calculate it ahead of the first bend. Typically the K-Factor is going to be between 0 and .5. In order to find the K-Factor you will need to bend a sample piece and deduce the Bend Allowance. The Bend Allowance is then plugged into the above equation to find the K-Factor. 1. Begin by preparing sample blanks which are of equal aSee more on sheetmetal.meHow is the hardness of ar400 steel determined?It has a lower hardness of 360 444 BHN. As with other abrasion resistant steels, it does not have a defined chemistry, but rather, grade is determined based on hardness. In addition to its general characteristics of being formable, while maintaining good abrasion resistance, AR400 steel also has the following mechanical properties:See all results for this questionHow big of a bend do I need for an ar400 steel plate?Up to .75" can be cold bent to minimum inside bend radius of 3t (where t is the plate thickness) with the bend axis transverse to the rolling direction. A radius of 4t can be used when bending parallel to the roll direction. For plate over .750" a radius of 6t is recommended when forming transverse to the rolling direction.See all results for this question
