Stainless Steel

We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

Stainless steels have an extended historical past of application involved with water due to their glorious corrosion resistance. Applications embody a spread of situations including plumbing, potable water and wastewater therapy, desalination, and brine treatment.

However, over time, rust can and will develop on stainless steel. To forestall stainless-steel from rusting, you should passivate it. Passivating stainless-steel is a course of that permits stainless steel to retain its corrosion resistance. Precipitation hardening stainless-steel could be strengthened and hardened by heat therapy.

Types 304 and 316 stainless steels are commonplace supplies of building in touch with water. However, with growing chloride contents, larger alloyed stainless steels corresponding to Type 2205 and tremendous austenitic and super duplex stainless steels are used. The minimal 10.5% chromium in stainless steels provides resistance to approximately seven hundred °C (1,300 °F), whereas 16% chromium provides resistance up to approximately 1,200 °C (2,200 °F). Type 304, the commonest grade of stainless-steel with 18% chromium, is resistant to approximately 870 °C (1,600 °F).

The high Chromium and Nickel content of the grades in this group present superior corrosion resistance and very good mechanical properties. They can’t be hardened by way of heat remedy, but can be hardened considerably via cold-working. None of the grades in this class are magnetic.

The commonest forms of stainless steels are austenitic stainless steels. Compared to other forms of stainless steels, austenitic stainless steels are extraordinarily high in nickel content. Generally, they may also include high quantities of chromium, nitrogen, and molybdenum.

These grades are straight Chromium steels with no Nickel, and are sometimes used for ornamental trim, sinks, and certain automotive purposes such as exhaust methods. Martensitic Stainless grades are a group of stainless alloys made to be be corrosion resistant and harden-able (utilizing warmth treating). All martensitic grades are straightforward chromium steels without nickel. Martensitic grades are mainly used where hardness, strength, and put on resistance are required.

Applications For 304 Stainless Steel

The presence of molybdenum additional enhances the resistance to corrosion in an acid medium. The most common grades are 304/304L and 316/316L. The “L” grades are used to provide further corrosion resistance after welding. The letter “L” after a stainless-steel grade quantity signifies low carbon. Carbon levels are kept to .03% or underneath to keep away from carbide precipitation, which may lead to corrosion.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
