3 Algoma s heat treat facility is registered to TS s heat - Treated Plate is rapidly quenched by 40,000 gallons of water per minute, sprayed under high pressure on both top and bottom surfaces simultaneously, over the full surface of the Plate . This unique quench system is part of a process that enables Algoma to deliver heat - Treated Plate with user-friendly characteristics and longer life in abrasive applications. Rapid cooling ensures through-thickness hardness, and the virtually scale-free surface allows easy flame-cutting and welding without surface preparation. Essar Steel Algoma offers fast, direct shipping to all of North America by rail, road or water, plus full technical support from a team of technical service representatives, development engineers, and product InformationWeldingAlgoma s heat - treat facility produces a low alloy Plate that is easy to weld using simple procedures and common, readily available carbon contents and carbon equivalents of Algoma heat - Treated plates are similar to those of many medium- and high-strength alloy carbon steels.

4 A high resistance to hydrogen-induced cold cracking is inherent when proper welding procedures are employed as outlined in the next sound welds depend on good joint preparation, the temperature of the material, joint restraint and the use of the appropriate low-hydrogen consumables. Please consult your welding consumable supplier for the appropriate heat input processes such as electrogas and electroslag should not be used, as they can adversely affect Plate properties in and adjacent to the heat affected a weld will be exposed to abrasives, most of the joint can be filled with lower-strength material, with a capping layer of abrasion-resistant weld metal applied to complete the heat - Treated steels are sensitive to heat : in welding, stress relief and elevated temperature service. Holding the Steel at or near stress relieving temperatures for any length of time will result in lower mechanical properties.

5 The length of time at temperature will determine the potential flame cut heat - Treated Plate that is going to be subjected to dynamic loading, forming, or restraint during welding, it is recommended that the Plate edges be ground or machined to remove the hardened layer that results from the cutting cuttingAll grades of Algoma heat - Treated Plate are easy to cut using the proper shop and field recommends the smallest possible torch tip combined with the fastest possible cutting speed to flame cut Algoma heat - Treated Plate , since all heat - Treated Plate products are sensitive to heat . A small tip will minimize the heat effect and ensure minimal degradation of the Steel s inherent s virtually scale-free surface will improve the smoothness of the oxyfuel cut and will generally eliminate blowback. For multiple cuts, balanced torch settings will minimize ResultsHow to get the best results with Essar Steel Algoma s heat Treated Mn6Cu + Ni15Cr + Mo + V5C+=++The carbon equivalent on the data sheets for each grade is calculated using the Deardon O Neil formula:Hardness 60 0 40 0 30 0 20 0 60 0 50 0 40 0 30 0 20 0 2 46 8 10 12 14 16 mm 50 0 HBHv AlgoTAlgoTAlgoTuf 500uf 450F uf 400F Algoma 100/130 Distance from edge Measured at midthickness, 3/8 ( mm) min.

For AlgoTuf 400F plates (38mm) and thicker, AlgoTuf 450F plates (16mm) and thicker and all thicknesses of AlgoTuf 500, a preheat temperature of 210 F (100 C) is and punching Both Algoma 100 and 130 grades, up to (12mm), can be either sheared or punched using equipment of sufficient capacity. The punch diameter should be at least times the Plate thickness. Tools must be kept in good working order and operator safety measures must be followed. Algoma does not recommend that the AlgoTuf grades be either sheared or punched because of their high strength and hardness levels.

7 Excessive tool wear, broken punches and/or damage to the shear or punch equipment could (see the machining chart)Algoma heat - Treated Plate is easy to machine, using the proper cutting tools, speeds and feed rates. Cutting speeds greater than Algoma s recommendations can cause rapid tool deterioration. Liberal amounts of a good coolant are to its extreme hardness, AlgoTuf 500 is rarely machined. Algoma recommends the following milling speeds, feed rates, etc., for its heat - Treated Plate grades, depending on the type of cutting tool (see the drilling chart)Algoma heat - Treated Plate can be drilled easily, using the recommended drill speeds and feed rates of the attached table. Higher cutting speeds may cause rapid deterioration of drill to table: 1. Centre punch the Steel Plate prior to drilling. 2. Ensure the workpiece is fully restrained. 3. Ensure liberal amounts of coolant are Algoma heat - Treated Plate is tested according to CAN/CSA , and/or ASTM A6 standards.

9 The clean surface of Algoma s Plate permits easy welding and flame cutting without surface better than A6 flatnessAll grades of Algoma s heat - Treated Plate are supplied to 1/2 ASTM A6 flatness tolerances, an important characteristic where flatness is a critical requirement for end hardness for products that really lastAlgoma produces several grades of abrasion-resistant Plate that are throughhard over most of the thickness range. This attribute translates into longer service life and generates cost savings that result from a longer product life s heat - Treated , abrasion-resistant Plate grades achieve their final hardness without work variation in core hardness may be encountered in the AlgoTuf 400F and 450F grades >= (>=57mm) and in the AlgoTuf 500 grade over (32 mm).Algoma s standard practice is to take hardness checks after the removal of ( ) from the Plate abrasion resistanceAbrasion-resistance is an important quality of Algoma s heat - Treated Plate .

10 But abrasion resistance is just the starting point. Many different metallurgical factors must be balanced with the demands of many different applications to create the best situations subject Steel to different types of wear. For example, the rolling contact wear experienced in railroad rail is different from the high stress abrasive wear encountered by mining equipment. For this reason, it isn t possible to predict absolute wear rates for various steels. Instead, Algoma provides generalized relative performance data based on experience, published literature and standardized tests, performed on various Steel grades under high and low stress test following chart shows the ability of Algoma s heat - Treated Plate grades to resist high- and low-stress abrasion. The chart uses SAE 1016 as a reference for low-stress conditions and Algoma 100 (equivalent to ASTM A514 Grade S) as reference for highs stress most Plate applications, the dominant factor in determining abrasion resistance is the hardness difference between the Steel and the material being handled.
