The establishment of a correct method for evaluating the life of pre hardened tool steel p20 requires the preparation of criteria related to the strength and cracks of pre hardened tool steel p20, mechanical damage mechanisms, corrosion mechanisms, and mathematical models of fatigue crack growth, etc., which are compiled into computer programs. In the process of programming the program, it is required to select the operating parameters, plates, reinforcement accessories, metal properties, corrosion levels, mechanical damage defects and other data of the oil storage tank under various conditions.

H-13, P-20, 420ss - Alloy Tool Steel Inc. P-20 has a machinability rating of 65% of a 1% carbon tool steel. P-20 is sold in the pre-hardened condition. Typical annealed hardness is BHN 2861301 Rc 30/32. P-20 maximum working hardness is BHN 301 Rc 32 (Further heat treating is not normally required). P-20 incapable of meeting ASTM-A681. AISI P20 Steel - DIN 1.2311 - SCM4 - Songshun Steel Just Pre-hardened steel can meet the needs of the industry. The die life can reach 50W mode times. 1.2311 Tool Steel Forging. 1.2311 steel plate and round bars materials are forged at 1093C (2000F) down to 899C (1650F). Forging below 871C (1600F) is not recommended for these steels P20 material. P20 Steel Round Bar Sheet Plate Heat pre hardened tool steel p20
Pre-hardened type tool steel for plastic mold. mold for high quality plastic with long run production. LKM 2312: P20 + S: Prehardened: 29-35: Excellent machinability, most suitableable for high speed volume machining. Plastic mold for general use and core parts: LKM 738: P20 + Ni: Prehardened: 29-35: High quality pre-hardened type tool steel pre hardened tool steel p20 P20 Tool Steel - P20 high tensile tool steel - Steel Express P20 TOOL STEEL - Flats & Squares. P20 (1.2311) Pre hardened to approximately 300 B.H (65 t.s.i) P20 requires no further heat treatment therefore avoiding risk of distortion or cracking. Although pre-hardened P20 is still capable of being machined and of giving a good polished finish. Typical applications:Plastic moulds, backers, bolsters, die pre hardened tool steel p20 P20 Steel | P20 Steel Plate P20 a versatile steel commonly used in the production of large mould frames & bolsters. Characteristics. Characterised by good toughness at moderate strength levels, P20 tool steel is a highly versatile engineering material. The alloy is a pre-hardened plastic mould steel and provides unified hardness across wide sections.
P-20 HI HARD is mold quality alloy steel supplied in the prehardened condition. Special melting and refining practices are utilized to produce a uniform product with exceptional cleanliness. These characteristics allow P-20 HI HARD to be polished to an extremely high finish required for plastic molding. The material is tested to rigorous tool steel standards to ensure uniformity of structure pre hardened tool steel p20
Different form pre hardened tool steel p20, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.
