Description:
HAOSTEEL GROUP CO., LIMITED has different material grades of
stainless steel coil, provide very comprehensive stainless steel
products for you, you can find the complete specifications, the
quality of the products with high performance and high quality, and
can be tailored, if you need more product information, including
automotive, petrochemical, electronics and pharmaceutical, and
stainless steel products manufacturers, such as building suppliers
and general engineering company, in order to meet the various
needs.
There are various types of stainless steel, which can be divided into several types according to the structure at room temperature.Martensite or ferritic body type: 430, 420, 410, etc.The austenite body is magnetic or weak, and the martensite or ferrite is magnetic.A 304 stainless steel coil is an austenitic type of steel coil that is non-magnetic or weakly magnetic.
As a kind of widely used steel, 304 stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties.Punching, bending, such as hot workability is good, no heat treatment hardening phenomenon (using the temperature to 196 ℃ ~ 800 ℃).Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavy pollution area, it needs to be cleaned in time to avoid corrosion.Suitable for processing, storage and transportation of food.304 stainless steel is a common material of stainless steel, the density of 7.93 g/cm3 and resistance to high temperature 800 ℃, has the processing performance is good, the characteristics of high toughness, widely used in medical industry and furniture decoration industry and food industry

Surface feature fabrication for general purposes
NO.1 silvery white, matte hot rolled to the specified thickness, and then annealed and descaled a rough, matte surface that does not need to have a surface gloss
NO.2D silver-white cold rolling is followed by heat treatment and pickling, and sometimes the final light rolling is carried out on the woolen roller.2D products with NO light surface are used for the purpose of less stringent surface requirements, and are generally used for materials and deep blanking
NO.2B luster is stronger than NO.2D NO.2D after processing, the final mild cold rolling is carried out through the polishing roller to obtain proper luster.This is the most commonly used surface finish, which can also be used as a first step in polishing.The general material
BA shine is non-standard, but it is usually treated with bright annealing, and the surface is highly reflective.Building materials, kitchenware
NO.3 rough grinding will NO.2D and NO.2B materials, grinding construction materials and kitchen utensils with 100~200# abrasive grain abrasive belt
NO.4 intermediate grinding will NO.2D and NO.2B materials, polishing surface obtained by grinding with 150~180# abrasive grain abrasive band, which is universal. The polished surface with visible 'grain' with mirror reflection is the same as above
HL hair grain grinding suitable particle size grinding materials hair grain grinding (150~240#) many buildings, building materials
No.7 is close to mirror grinding with 600# rotary polishing wheel for fine art and decoration
NO.8 mirror lapping mirror lapping mirror with polishing wheel, for decoration
