With the type 2.1, declaration of compliance with the order, document the producer declares that the products are in accordance with the order. In this, the charge number of the products is given but neither the test report
With the type 2.2 test report document, document the producer declares that the products are in accordance with the order. In the test report the quality control test results based on non- specific inspection are given, in accordance with the general material standards. The test results are not necessarily those from the lot supplied to the customer.
With the type 3.1, inspection certificate producers declares that the products are in accordance with the order. The relevant test results and chemical analysis results are presented in this document.
In the type 3.2 inspection certificate both the producer and either an inspector authorised by the customer or designated by the official regulations certify that the products are in accordance with the order.
304 stainless steel is the most common stainless steel. The steel contains both chromium (usually 18%) and nickel (usually 8%) metals as the main non-iron constituents. It is an austenite steel. It is not very electrically or thermally conductive, and is non-magnetic. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.
Type 316—the second most common grade (after 304); alloy addition of molybdenum prevents specific forms of corrosion. It is also known for its increased resistance to chloride corrosion compared to type 304.
Type 316L—is an extra low carbon grade of 316, generally used in the fabrication of pressure vessels for boiling water reactors, due to its high resistance to corrosion. It is immune to grain boundary carbide precipitation. This makes it suited to use in  welded components.
An independent, not-for-profit corporation dedicated to advancing hygienic equipment design for the food, beverage, and pharmaceutical industries.
Alloy 904L is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L are not adequate. The addition of copper to this grade gives it corrosion resistant properties superior to the conventional chrome nickel stainless steels, in particular to sulphuric, phosphoric and acetic acids. It also has a high resistance to pitting in chloride solutions, a high resistance to both crevice and stress corrosion cracking.
The predominant alloying ingredient is nickel. The primary function of the Hastelloy super alloys is that of effective survival under high-temperature, high-stress service in a moderately to severely corrosive, and/or erosion-prone environment, including the pressure vessels, chemical reactors, distillation equipment, and pipes and valves in chemical industry.
