There are several manufacturers available that are manufacturing a wide range of plates in different grades and material. But, Triton alloys are one of the best manufacturers available worldwide. They offer the most demanding and popular type of mild steel grade plates is SS400 plates that are widely used in numerous industries and applications. This steel grade is considered best due to its excellent performance and quality it offers. It has increased corrosion resistance and high tensile strength.

SS400 are one of the most and widely been utilized alloy all over the world. The ss400 steel plates can be regarded as SS 400 plates that comprise of low alloy steel and carbon. These steel plates are used to form containers that have the capacity to bear even the lowest of the temperature in seawater.

Basically, these plates are special kind of mild steel plates that can be used for general structuring and it can even be used in bridge, house, and ship making. This steel plate possesses incredible features which make working in tough as well as severe conditions as well as the environment. The structure has the capacity to bear certain temperature as well as pressure ranges.

The 400 series of stainless steel typically contains 11% chromium as well as 1% manganese and is kept above 300 series. The stainless steel 400 series tend to show susceptibility toward rust as well as corrosion under extreme conditions followed by heat treatment.

There is a relationship between abrasion resistance and surface hardness related to stainless steel 400 plates. The abrasion resistance is generally expressed in a ratio, with an increase in hardness grade, the abrasion resistance also increases. Higher abrasion resistance can be achieved by well-structured combination along with appropriate technology.

Cold bending forming of SS 400 plates is possible through press methods as well as roll bending method. However, utmost care is considered while processing and the user are allowed to refer to the product catalog. The stainless steel plates achieve easy adjustment in all conditions while forming and getting improved forming through strict control hardness within narrow ranges.

High strength and high hardness of steel plates can be displayed through sensitivity at low temperature cracking. Crack-free welding of 400 plates is possible so as to perform well in applications. In heat affected zone or weld metal, low-temperature cracks get occurred when the region is embrittled via hydrogen penetration during welding. The result can be based on arc welding through ultra-low welding and gas metal arc weld via solid wire.

The series absorb energy at guaranteed temperature via refinement of steel microstructuring through micro-alloying technology. Low-temperature toughness is apt to decrease when the thickness of the plate got increased with conventional technology. The series contributes improved safety as well as longer life of structure in industrial machinery.

The test that usually got performed on plates is a hydrostatic test, destructive test & nondestructive test Charpy test, hardness test, tensile test, mechanical test positive material test. Other tests include micro and macro test, intergranular corrosion test, a chemical test or spectro analysis flaring test, flattening test, radiographic test, ultrasonic test, pitting corrosion test & visual inspection.

Documentation is specification guide, commercial invoice, packing list like net & gross weight, quantity marks & number, fumigation certificate, MTC report in accordance with en 10204 3.2 or 3.1, NABL test report and guarantee letter.

Certificate origin by top manufacturer, raw material test report, attested certificate by exporter, mill test report, quality assurance plan, & heat treatment charts are some certificates offered.

The packaging of SS 400 plates is done using wooden boxes, cartons, crates and cases, pallets cores, individual pole wrap, and spiral wound wrapping.
