Global stainless steel production
According to statistics from the International Stainless Steel Forum (ISSF), the compound annual growth rate of global stainless steel production from 1950 to 2011 was 5.8%, higher than that of ordinary carbon steel by 3%. In 2002, global crude stainless steel production exceeded 20 million tons for the first time, reaching 20.69 million tons. In 2010, the total output reached 31.09 million tons, and in 2014, the total output exceeded 40 million tons, reaching 41.7 million tons. In 2018, it broke through the 50 million mark and reached 50.7 million tons. It is estimated that the global crude stainless steel production will exceed 60 million tons in 2020.
Before the second round of global stainless steel production capacity expansion in 2000, the European region dominated the global stainless steel production for a long time, and its weight ranked first in the industrial structure. Since then, stainless steel production capacity and output in Asia began to increase, while the ratio of traditional stainless steel production areas such as Europe and the United States to the world's total production continued to decline. In 2005, the proportion of Asia's production in the world exceeded 50% for the first time.
Situation of major overseas stainless steel enterprises
The distribution of global stainless steel factories mainly includes France, Germany, Italy, Belgium, Sweden, Finland, Spain, etc. in Western Europe; China, Japan, Korea, Taiwan, India, etc. in Asia; South Africa in Africa; Brazil in America and the United States. Europe: Outokumpu, Acerinox, Aperam; Asia: Nippon Steel (Japan), Posco (Korea), Yieh United Steel Corp (Taiwan), Jindal Stainless Steel (India)
Global stainless steel consumption
In the global stainless steel consumption structure, stainless steel products and medical equipment account for the largest proportion of 48%, followed by chemical and petrochemical products at 16%, infrastructure construction at 15%, automobiles and transportation at 10%, and industry at 8%. %, and 3% for other industries.
Global apparent consumption and demand indices for all stainless steel products are still expected to increase slightly. The main driving force comes from developing countries, such as China and India, or other Southeast Asian countries, Europe and the United States, whose stainless steel consumption is mature and has limited growth potential.
What are the commonly used grades of stainless steel?
201: Manganese-nickel stainless steel, with certain acid and alkali resistance, high density, polished without bubbles, used in watch cases, decorative pipes, industrial pipes and other shallow stretched products.
202: It belongs to low-nickel and high-manganese stainless steel, with nickel and manganese content of about 8%. Under weak corrosion conditions, it can replace 304. It is cost-effective and is mainly used in architectural decoration, highway guardrails, municipal engineering, glass handrails, road facilities, etc.
304: General-purpose stainless steel with good corrosion resistance, heat resistance, low-temperature strength, good mechanical properties, and high toughness. It is used in the food industry, medical industry, industry, chemical industry, and home decoration industry.
304L: Low carbon 304 stainless steel, used in equipment parts with corrosion resistance and formability.
316: Added Mo, excellent high temperature corrosion resistance, used in seawater equipment, chemistry, food industry, and papermaking fields.
321: It has excellent high temperature stress breaking performance and high temperature creep resistance performance.
430: heat fatigue resistance, thermal expansion coefficient is smaller than austenite, used in household appliances, architectural decoration.
410: High hardness, toughness, good corrosion resistance, high thermal conductivity, small expansion coefficient, and good oxidation resistance. It is used to manufacture parts that are corrosive to atmosphere, water vapor, water, and oxidative acids.
