INTRODUCTION Hongkong Ruikun Holdings Group Co., Ltd. is modern enterprise focusing on steel trading and investment internationally. We are performance as wholesaler, stockist, agent, processing and logistics company and being as strategic sales partner of over 30 mills worldwide. Shanghai Ruikun Metal Materials Co., Ltd., one of the largest member of our group, mainly doing steel products in hot rolled series, cold rolled series, stainless steel and constructional steel materials. Keeping good partnership relations with Baosteel, Wisco, Ansteel, Shasteel, Sinosteel, POSCO, NSC etc., and good resources help us being one of the top steel trading company in recent years. We operate depends on "honest & trusty", "win-win" model all the time, thus makes us a good reputation in steel industry in China. We sale over 300,000 tons every year and developed several subsidiary companies or office in costal cities in China. We hope to cooperate with steel trading or end user companies worldwide. Aiming at a long term, stable, both-win partner for steel business.

SS STEEL Applicable Standard of Products: Japanese industrial standard ： JIS G4305-1999 Chinese specification(GB) American specification(ASTM 、 AISI) European specification EN100882 GradeCharacteristicsApplication SUS301HTSUS304HT High hardness, high strength ， and high fatigue strength Automobiles, electronic products,and spring sheet steel SUS304 Widely used; corrosion resistant 、 heat resistant, good mechanical properties in low temperature, good drawabity and bending treatment properties without thermal treatment hardening, no- magnetic Domestic appliances (Kitchen utensils of category 1 and 2), cupboard, indoor pipes, heater, boiler, automobile parts, medical apparatus, building material, chemical equipments, food processing industry, agriculture, watercraft parts SUS304Cu With the addition of Cu, 304Cu has good formability, in particular good deep drawablity Domestic appliances 、 thermos bottles 、 kitchen sinks 、 bathtub etc SUS304Ni9 304Ni9 made is created by increasing the Ni content in 304,has good formability, in particular good deep drawablity Domestic appliances 、 thermos bottles 、 kitchen sinks 、 bathtub etc SUS304L 304L is made by lower carbon 304 type.Better intergranular corrosion resistance than 304, it possesses corrosion resistance properties without undergoing heat treatment Machinery and tools used in the chemical 、 coal and petroleum industries that require intergranual corrosion resistance, building material, heat resistant parts and parts that are difficult to heat treat SUS316 Higher corrosion resistant, higher-heat resistant, can be used in very severe conditions, with less work hardening, no-magnetic Sea water treatment equipments, chemical industry, dye making, paper mill, herbal acid, fertilizer production equipments, photography, food processing industry, coastal installations SUS316L 316L is made by lower carbon 316 type. Better intergranular corrosion resistance than 316, can be used in very severe conditions, with less work hardeding, no-magnetic Sea water treatment equipments, chemical industry, dye making, paper mill, herb acid, fertilizer production equipments, photography, food processing industry, coastal installations SUS321 With the addition of Ti, thereby prevent intergranular corrosion. Heat- resistant, high-temperature resistant and antioxidizing in high- temperature Heat-resistant material,???? automobiles, aerocraft ventilation pipings, boiler cover, pipings, chemical devices and heat-exchanger SUS301 301 steel has lower Cr? Ni content than 304.lts strength increased by cold working Trains, aircraft, belt converyors, vehicles spring SUS301L 301L is made by lower carbon 301 type. Better intergranular corrosion resistance than 301, strength increased by cold working Frame of Trains, building exterior material
