Stainless steel casting are the United Kingdom from the 19th century metallurgical expert Henry • Blair invention, up to now has been the development of more than 100 historical noodle. Since the formation of an ordinary metal oxide on the surface after so corrosion expansion and
eventually the formation of holes, Henry • Blair to use paint or oxidation-resistant metals (such as, zinc, nickel and chromium) to ensure the steel plating to the surface, but, as people know,
such protection is only a thin film. If the protective layer is damaged, the following will start rusting steel. Resistance put our air, steam, water and other corrosive media and the weak acid,
alkali, salt, chemical etching medium, such as corrosion of steel known as acid-resistant stainless steel, but often one of the weak corrosive medium corrosion-resistant steel known as stainless
steel, and will be corrosion-resistant steel chemical mediator known as acid-resistant steel. Stainless steel casting so far this family has 4 large system: Ferritic Stainless steel casting, is the 12% chromium 30%. Its corrosion resistance, flexibility and weldability are with the amount of chromium increases, chloride stress corrosion resistance is superior to other
types of Stainless steel casting; Austenitic Stainless steel casting, is the chromium is greater than 18 %, also contains 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements, Stainless steel casting such a good performance can be corrosion resistant to a variety of media; Austenitic - Ferritic Duplex Stainless steel casting, is the the above characteristics of the two to be integrated, to produce superplasticity with Stainless steel casting; Martensitic Stainless steel casting, although the high intensity, but the plastic and poor solderability. Stainless steel casting materials are materials in one of the highest intensity, because of its good corrosion resistance, structural components so that it can permanently maintain the integrity of
engineering design by the architect and engineering Everbright designers of all ages.

Soldiers, the country's major event in the life and death,
the survival of the Road, also must be aware of. Chinese evolutionary history of five thousand years of civilization, but also the history of five thousand years of war, the ancients said, "For
their good work, the first benefit of its browser," not only rely on the people of war and, more importantly, depend on the level of manufacture of weapons, from the Copper casting Iron casting to Steel casting. Spring and Autumn Period, when the widespread use of National
Copper casting the weapons, although such weapons into a degree must improve on the
combat effectiveness of the Copper casting weapons but there is a big disadvantage, because the reserves of copper
are not very rich, large-scale equipment to the armed forces With some difficulty, at the same time its very brittle will be broken as soon as excessive force. These conditions have led to weapons
of Iron casting to be a lot of the market, some big powers gradually equipped with such
weapons, because there is no Iron casting Yi Copper casting off the effects of confrontation at a great advantage, gradually
equipped with weapons of National Iron casting annexation of a number of such weapons and equipment can not afford the
country. From this time into the Spring and Autumn Warring States period, China's feudal society started its long rule. With Chinese from all walks of life in the Iron & P class,
Iron casting higher level of Steel casting has emerged slowly, Steel casting the weapons in the Tang Dynasty are the most famous knife, it is the
emergence of the history of cold steel on the impact on future generations unprecedented weapons, Tang knives are essential as the military equipment of war materiel and military artifacts, as the
mid-Tang, is strictly prohibited and possession of non-governmental private building, and its predecessor are the Han Dynasty against the Xiongnu cavalry Bujun main - Guards heavy infantry sword of
cutting horse evolved. Tang double-edged sword, one meter long handle 20. Tang army knife as a separate battle in the war against forces in the mid-Tang Tangjun twilight of the battle, the Han Tang
knives are nomadic peoples and to change his war horse disadvantage small ill-equipped to play a key advantage of many infantry weapons , the actual evolution of the war are weapons of war with the
evolution of forms of development, with the overall national strength and prosperity and the decline of Change. Since Tang Steel casting knives are weapons, and prosperity in the Tang Dynasty, when
Steel casting because the high cost and technological requirements are too high and
just focus on equipment, but not full equipment, the Song Dynasty unified the Central Plains, the Chinese cold-start a new round of weapons of the development of substantial new spears, long
knives, ax ax, God and the birth of arm crossbow armed Song Jun, ornate street knife arena has not repealed, but the rise in Japan, but slowly

Satisfied customers in order to Gray
iron casting for the needs of our client companies in the first
principle of business organizations, the backbone of the Gray iron casting for research conducted through the efforts of everyone at the failure of constant, we finally cast
out of the company has Casting a good performance, good vibration, good wear resistance, good machining performance, low sensitivity gap Gray
iron casting. By the relevant state departments to identify their
quality, we Gray iron casting production has exceeded the level of domestic industry, closer to international standards.
Gray iron casting of our matrix structure by the
different gray cast iron is divided into three categories: ferrite matrix of gray cast iron; one pearlite ferrite matrix of gray cast iron; pearlitic gray cast iron matrix. Gray
iron casting and the mechanical properties of the matrix organization
and the form of graphite has a close relationship. Gray iron casting for the flake graphite matrix of fragmented serious monoceras Department at graphite cause stress
concentration, so that Gray iron casting in the tensile strength, plasticity and toughness should be much lower than steel, but the
compressive strength and steel do considerable, so that became Gray iron casting cast iron used in the mechanical properties of the worst pieces of cast iron. But at the same time,
matrix Gray iron casting for the mechanical properties must also have the effect of ferrite matrix graphite of gray cast iron
because of its thick film, the strength and hardness of the minimum, so fewer applications; pearlitic gray cast iron matrix small piece of graphite, have higher strength and hardness, mainly to be
used to make casting more important; one pearlite ferrite matrix graphite of gray cast iron gray iron tablets than the micro-coarse pearlite, pearlite than gray cast iron performance. It is more
used in industry are pearlite matrix of gray cast iron.
