SUS碳素結(jié)構(gòu)鋼/ Sus stainless heat resistant steel

不銹鋼模具鋼是用來制造冷沖模、熱鍛模、壓鑄模等模具的鋼種。模具是機(jī)械制造、無線電儀表、電機(jī)、電器等工業(yè)部門中制造零件的主要加工工具。模具的質(zhì)量直接影響著壓力加工工藝的質(zhì)量、產(chǎn)品的精度產(chǎn)量和生產(chǎn)成本，而模具的質(zhì)量與使用壽命除了靠合理的結(jié)構(gòu)設(shè)計(jì)和加工精度外，主要受模具材料和熱處理的影響，SUS斯尤斯模具鋼采用海外原材料，高精度、高韌性、耐腐蝕、高質(zhì)量的模具鋼新品種大大降低了采購成本。

Die steel is used to make cold stamping die, hot forging die, die casting die and other steel. Mold is the main processing tool for manufacturing parts in mechanical manufacturing, radio instruments, motors, electrical appliances and other industrial sectors. The quality of mold directly affects the quality of pressure processing technology, product precision, output and production cost. Besides reasonable structure design and processing precision, the quality and service life of mold are mainly affected by mold materials and heat treatment. The new varieties of mold steel with high precision, high toughness, corrosion resistance and high quality are greatly reduced by using overseas raw materials Lower procurement costs.

按模具服役條件將模具鋼分為四大類，美國(guó)金屬學(xué)會(huì)工具鋼委員會(huì)列出了：冷作模具鋼、熱作模具鋼、塑料模具鋼、塑膠模具鋼等四大類。其中，冷作模具鋼又分出12小類，熱作模具鋼9小類，塑料模具鋼2小類，塑膠模具鋼5小類。每個(gè)小類的選材又取決于三個(gè)主要因素：

◆ 尺寸大小和形狀的復(fù)雜性。

◆ 被加工的材料。

◆ 耐久性要求或設(shè)計(jì)壽命。 [1] 冷作模具鋼（1）分為五組：W組、O組、A組、D組、S組。

◆ W組即水淬模具鋼，有11個(gè)鋼種，7個(gè)碳素模具鋼，含碳量從0.7%-1.3%。

◆ O組即油淬冷作模具鋼（俗稱油鋼），有4個(gè)鋼種，含碳量在0.85%-1.55%，

◆ A組即空淬中合金冷作模具鋼，有9個(gè)鋼種，含碳量從0.5%-2.25%。

◆ D組即高碳高鉻冷作模具鋼，有7個(gè)鋼種，含碳量0.9%-2.5%。

◆ S組即耐沖擊工具鋼，有7個(gè)鋼種，含碳量0.4%-0.6%。用于冷作模具還有高速鋼（HSS組）和超高速鋼（SHSS組），鈷基硬質(zhì)合金和鋼結(jié)硬質(zhì)合金（HA組），粉末鋼和工程陶瓷（PIM組），碳鎢工具鋼（F組），特殊用途工具鋼（L組）。

According to the die service conditions, die steel is divided into four categories. The tool steel Committee of the American Society of metals lists four categories: cold working die steel, hot working die steel, plastic die steel and plastic die steel. Among them, cold die steel is divided into 12 sub categories, hot die steel is divided into 9 sub categories, plastic die steel is divided into 2 sub categories, plastic die steel is divided into 5 sub categories. The selection of each sub category depends on three main factorsComplexity of size and shape,Materials processed,Durability requirements or design life. [1]Cold working die steel(1) They were divided into five groups: Group w, group O, group A, group D and group s.Group W, namely water quenched die steel, has 11 grades and 7 carbon die steels, with carbon content ranging from 0.7% to 1.3%.Group O, namely oil quenched die steel (commonly known as oil steel), has four kinds of steel with carbon content of 0.85% - 1.55%,Group A, i.e. air quenched medium alloy cold working die steel, has 9 grades with carbon content ranging from 0.5% to 2.25%.Group D, high carbon and high chromium cold working die steel, has 7 grades with carbon content of 0.9% - 2.5%.Group s, i.e. impact resistant tool steel, has 7 grades with carbon content of 0.4% - 0.6%.

產(chǎn)品用途/ Case study:

廣泛的運(yùn)用于加工模具時(shí)用，由于模具的用途很廣，各種模具的工作條件差別很大，所以，制造模具用材料范圍很廣，在模具材料中應(yīng)用最廣的當(dāng)屬模具鋼。從—般的碳素結(jié)構(gòu)鋼、碳素工具鋼、合金結(jié)構(gòu)鋼、合金工具鋼、彈簧鋼、高速工具鋼、不銹耐熱鋼直到適應(yīng)特殊模具需要的馬氏體時(shí)效鋼以及粉末高速鋼、粉末高合金模具鋼等。模具鋼按用途一般可分為冷作模具鋼、熱作模具鋼和塑料模具鋼三大類。

Widely used in the processing of molds, because the mold has a wide range of uses and the working conditions of various molds are very different, so the range of materials used for manufacturing molds is very wide, and the most widely used in mold materials is mold steel. From general carbon structural steel, carbon tool steel, alloy structural steel, alloy tool steel, spring steel, high-speed tool steel, stainless heat-resistant steel to maraging steel, powder high-speed steel, powder high-alloy die steel, etc. Die steel can be generally divided into three categories: cold work die steel, hot work die steel and plastic die steel.
