304, 304H, and 304L all possess the same nominal chromium and nickel content and also possess the same corrosion resistance, ease of fabrication, and weldability. The difference between 304, 304H, and 304L is the carbon content, which is < 0.08, < 0.1, and < 0.035% respectively (also see UNS designations S30400, S30409, & S30403 respectively ...
300 series stainless steels are the larger subgroup. The most common austenitic stainless steel and most common of all stainless steel is Type 304, also known as 18/8 or A2. Type 304 is extensively used in such items as cookware, cutlery, and kitchen equipment. Type 316, also known as A4, is the next most common austenitic stainless steel.
There is a secondary market that recycles usable scrap for many stainless steel markets. The product is mostly coil, sheet, and blanks. This material is purchased at a less-than-prime price and sold to commercial quality stampers and sheet metal houses. The material may have scratches, pits, and dents but is made to the current specifications.

Fe – Cr Phase diagram. To qualify as stainless steel, Fe-base alloys must contain at least 10.5% Cr. The iron-chromium phase diagram shows that up to about 13% Cr, the steel undergoes successive transformations upon cooling from the liquid phase from ferritic α phase to austeni
304L is a low-carbon austenitic chromium-nickel steel designed for special applications. [30] 316L is a low carbon austenitic chromium-nickel steel with superior corrosion and heat resisting qualities. [31] 321 is an austenitic chromium-nickel steel with a high chromium content of 18.00%. [32] 400 series
A Allocation of costs is the transfer of costs from one cost item to one or more other cost items. Allowance - a value in an estimate to cover the cost of known but not yet fully defined work. As-sold estimate - the estimate which matches the agreed items and price for the project scope. B Basis of estimate (BOE) - a document which describes the scope basis, pricing basis, methods ...
According to the PMBOK (7th edition) by the Project Management Institute (PMI), Fixed Price Economic Price Adjustment Contract (FPEPA) is a "fixed-price contract, but with a special provision allowing for predefined final adjustments to the contract price due to changed conditions, such as inflation changes, or cost increases (or decrease) for special commodities".
