With a carbon content 0.50/0.60 this is a medium carbon steel which can develop a tensile strength of 700N/mm 45tsi. In the normalised condition En9 can be used for gears, sprockets and cams.

En9 commonly supplied in the as rolled condition. It can be flame or induction hardened to produce a high surface hardness with excellent wear resistance for a carbon steel grade.

In the normalised condition En9 can be used for gears, sprockets and cams.

AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. AISI 4140 alloy steel has high ductility. It can be formed using conventional techniques in the annealed condition. It requires more pressure or force for forming because it is tougher than plain carbon steels. the mechanical properties of this steel will be affected if it is welded in the heat-treated condition, and post-weld heat treatment should be performed. After the annealing is complete, the steel is heated to a molten phase again so that it can be poured into the desired form and can either be hot worked or cold worked through rollers or other tools to reach the desired thickness. Of course, there are other special operations that can be added to this to reduce mill scale or improve mechanical properties. AISI 4140 is a low alloy steel. Low alloy steels rely on elements other than just iron and carbon to enhance their mechanical properties. In AISI 4140, additions of chromium, molybdenum, and manganese are used to increase the strength and hardenability of the steel. The additions of chromium and molybdenum are why AISI 4140 is considered a “chromoly” steel.

Carbon steel is an alloy consisting of iron and carbon. The percentage of carbon in the steel affects the hardness, strength of elasticity and ductility of carbon steel. As the carbon percentage content rises, steel is harder and stronger but less ductile. Carbon steel has high hardness, toughness and strength, and it is relatively inexpensive compared to other steel. Carbon steel seamless pipes are extensively applied in the nuclear device, gas conveyance, petrochemical, shipbuilding and boiler industries, with characteristics of high corrosion resistance combined with suitable mechanical properties.

Applications:

Nuclear device
Gas conveyance
Petrochemical industries
Shipbuilding and boiler industries
Ship building and boiler industries

410 is the basic, general purpose stainless steel that is used for highly stressed parts and provides good corrosion resistance plus high strength and hardness. SS 410 contains a minimum of 11.5% chromium which is just sufficient enough to demonstrate corrosion resistance properties in mild atmospheres, steam, and many mild chemical environments. It is a general-purpose grade that is often supplied in the hardened but still machinable condition for applications where high strength and moderate heat and corrosion resistance are required. It displays maximum corrosion resistance when it’s been hardened, tempered, and then polished. Due to the hardening capabilities of this steel, other properties and the resulting performance of this material are somewhat compromised. The alloy can only effectively be used in mildly corrosive environments. It is the most widely used of the hard enable stainless steels. Heat treated 410 has mechanical properties comparable to the engineering alloy steel AISI 4130, coupled with the additional benefit of good corrosion resistance. 410 is highly resistant to atmospheric corrosion. Maximum corrosion resistance is obtained by hardening and polishing. Because 410 is an air hardening steel, it must be given a high preheat, at least 350-400°F before welding, and immediately given a full anneal before the weldment cools. Otherwise the metal will harden, and cracking is likely.

Features:

Readily welded by all standard methods.

Good corrosion resistance to atmospheric corrosion, potable water, and to mildly corrosive environments.

Its exposure to everyday activities (sports, food preparation) is generally satisfactory when proper cleaning is performed after exposure to use.

Good corrosion resistance to low concentrations of mild organic and mineral acids.

Oxidation resistant through 1500°F intermittently, 1200°F continuously.

Corrosion resistant.

Applications:

Applications requiring moderate corrosion resistance and high mechanical properties are ideal for Alloy 410. Examples of applications that frequently used Alloy 410 include:

Cutlery

Steam and gas turbine blades
