Boiler pressure vessel steel sheet is mainly used to manufacture superheater, main steam pipe and boiler fire chamber heating surface used in hot rolled medium thick plate material. Boiler steel plate is one of the very key materials in boiler manufacturing, mainly refers to the hot rolled special carbon steel and low alloy heat resistant steel medium thick steel material used to manufacture boiler shell, pot drum, box end cover, hanger and other important parts.It includes carbon steel, carbon manganese steel, microalloy steel, low alloy high strength steel and low temperature steel. Operating temperature is generally -20℃ to 500℃, individual up to 560℃. These are mainly 16MnR steel (16 manganese capacity low alloy steel, a type of steel), which is used in the manufacture of ASME code pressure vessels. 16MnDR is a kind of steel plate for cryogenic pressure vessel. 16Mn -- indicates that manganese content in steel plate is about 0.16%, D- indicates low temperature, R- indicates pressure vessel. (Usually, steel with a high content of a certain chemical element needs to be marked in the material, for example, 1.6% manganese is written as 16Mn, 16MnDR is used for -40 degree pressure vessel steel plate.

The manufacturer is not required to run the test unless it is specified on the purchase order (see Supplementary Requirement S7). Note that Practices A262 requires the test to be performed on sensitized specimens in the low-carbon and stabilized types and on specimens representative of the as-shipped condition for other types. In the case of low-carbon types containing 3% or more molybdenum, the applicability of the sensitizing treatment prior to testing shall be a matter for negotiation between the seller and the purchaser. Mechanical Test Mechanical test including heat treated condition, Transverse or Longitudinal Tension Test or Flatten Test. Transverse or Longitudinal Tension Test For lots of not more than 100 pipes, one specimen shall be taken for tensile testing.

Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the passive layer. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion. Stainless steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced formability and increased corrosion resistance.

Stainless steel is notable for its corrosion resistance, and it is widely used for food handling and cutlery among many other applications. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, or high-salinity environments. There are various grades and surface finishes of stainless steel to suit the environment the alloy must endure.

Generally speaking, only structural, tensile and deep drawing galvanized sheet have tensile performance requirements. The structural galvanized sheet requires yield point, tensile strength and elongation. Only elongation is required for stretching. Test method: The same as the general test method of thin steel plate, bending test: bending test is the main project to measure the process performance of sheet metal, but the national standards for all kinds of galvanized sheet requirements are not consistent, except structural grade, the rest are not required to bend and tensile test. In Japan, bending tests are required except for structural grade, architectural corrugated plate and general corrugated plate. Requirements: The general requirements of galvanized sheet bending 180, the outer surface shall not be separated from the zinc layer, the plate base shall not have cracking and fracture. Galvanized sheet is a steel plate coated with zinc. Is to prevent corrosion on the surface of the steel plate to prolong its service life, coated with a layer of metal zinc on the surface of the steel plate, is a kind of economic and effective rust prevention method, the zinc coated steel plate is called galvanized plate, galvanized coil plate and divided into no zinc flowers, small zinc flowers and zinc flowers. Zinc flower diameter 1~2mm zinc flower called small zinc flower. When the hot galvanized sheet comes out from the zinc pot, to the zinc layer without solidification spray or zinc powder, a water drop, a zinc powder particles will form a crystallization center, so that the unit area of zinc flowers increased and became smaller, so the galvanized surface will form with the naked eye can distinguish small zinc flowers, traditionally the product produced by this process is called small zinc flowers. Because this process often causes uneven zinc flowers, uneven surface color, and high production cost, so this process is not used much. (www.zhishanginternational.com) Large zinc flowers are not allowed to enter the finishing process. Small zinc flower or no zinc flower products through the finishing process, known as finishing zinc flower. This plate through the light of the galvanized sheet polishing machine, the galvanized sheet surface of the zinc flower flat is mainly used for color coated coil plate.
