When specifying stainless steel chemistry, it is important to reference the appropriate ASTM standard and the UNS (Unified Numbering System) number associated with the specific alloy or grade. UNS numbers are internationally recognized specific chemistry requirements.
Types 410, 420, 425 Mod, and 440A exhibit good corrosion resistance to atmospheric corrosion, potable water, and to mildly corrosive chemical enviroments because of their ability to form a tightly adherent oxide film which protects their surfaces from further attack.

Sandmeyer Steel Company stocks Alloy 310/310S, a multi-purpose austenitic heat resistant stainless steel with oxidation resistance under mildly cyclic conditions to 2010°F.
440C is a high carbon straight chromium high hardenability martensitic stainless steel, generally supplied in the annealed condition with a maximum Brinell hardness of 269 (Rc29) or annealed and cold drawn with a maximum Brinell hardness of 285 (Rc31).Characterised by good corrosion resistance in mild domestic and industrial environments, including fresh water, organic materials, mild acids
316 and 316L Stainless Steel Sheet, Coil & Bar - AMS 5524
316 / 316L are austenitic stainless steels that contain molybdenum, which increases their resistance to many chemical corrodents and marine environments. 316L is an extra low carbon version of 316 stainless steel. These materials are more resistant to general corrosion and pitting/crevices than conventional austenitic stainless steels. They also offer higher creep, stress-to-rupture and
ASTM A182 / A182M - 18a Standard Specification for Forged
1.1 This specification 2 covers forged low alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves, and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications that are referenced in Section 2.
SA-204; Overview. This carbon / molybdenum grade is used almost exclusively in Refinery / Petrochemical applications. The “lean alloy” characteristics of this grade lends itself to use in pressure vessels, fittings, and custom fabricated pipe and other environments within moderate temperature ranges.
17-4 Precipitation Hardening also known as Type 630 is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance.
A193 B7 Alloy Steel Round Bar. The ASME A193 designation covers fasteners intended for use in pressure vessels, valves, flanges, and fittings. Heat treated chromium-molybendum (AISI 4140) high-yield bolting steel for high pressure applications.
Differences between 316 and 316L Stainless Steel | Penn
Differences between 316 and 316L Stainless Steel. Posted on June 28, 2013. Tweet This. The differences between a 316L and a 316 straight grade are two-fold both in chemistry and mechanical properties. The L grade has a lower maximum carbon limit and the straight grade has increased mechanical properties.
Standard Specification for Stainless Steel Bars and Shapes
Abstract. This specification covers hot-finished or cold-finished bars except bars for reforging. It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels.
How To Passivate Stainless Steel Parts : Modern Machine …
Passivation remains a critical step in maximizing the essential corrosion resistance of parts and components machined from stainless steels. It can make the difference between satisfactory performance and premature failure. Incorrectly performed, passivation can actually induce corrosion
Chapter 6: Austenitic Stainless Steels / 71 removed routinely. Likewise, 302 gave way to the lower-carbon 304, for which the even lower-carbon 304L is commonly substituted and du-ally certiﬁed to qualify as either grade. While low carbon prevents sensitization, stabilized …
