08:09Which Indian steel plant has the largest installed steel production capacity
08:15A, C, राँर के लाई-स्तेल प्लांट
08:17B, भाई-जाग इस्तेल प्लांट
08:19C, भिलाई-स्तेल प्लांट
08:20D, दुर्कापूर इस्तेल प्लांट
08:44expense of ductility, toughness, both A and B, neither N or B.
08:51So, the right answer is C, both A and B, ductility and toughness.
08:58Purchase number is, annealing cannot soften the steel and improve machinability,
09:06relieve internal stress induced by rolling, forging or uneven cooling.
09:14C, remove coarseness of grain, D, none of this.
09:18So, this is the right answer, D, none of this.
09:2526, specific energy consumption in Indian steel plant is about,
09:31dash G calorie per ton crude steel.
09:35A, 7.0 to 9.5, 5.4 to 5, 12 to 13, 9 to 11.
09:45So, this is the right answer, D, 7.0 to 9.5.
09:51So, this is the right answer, hand-filled manganese steel.
09:54A, contains 12 to 14% manganese and 1% carbon, has great resistance to ORC, is used for rock
10:03drill and stone crusher.
10:05D, all A, B and C.
10:07So, this is the right answer, D, all A, B and C.
10:11Address number, high speed steel is softened by A, tempering at 400 degree centigrade, float by cleansing, B, normalizing at
10:22250 degree centigrade, C, annealing at 450 degree centigrade for 4 hours, float by low cooling, D, all A, B
10:32and C.
10:33So, this is the right answer, D, all A, which is the right answer, D, all A, which inhibits corrosion,
10:52chromium, silicon, nickel or carbon.
10:54So, this is the right answer, chromium.
10:59Next, this is the right answer, which is not an integrated steel plant.
11:04Radicular steel plant, bilay steel plant, durgapur steel plant, or salim steel plant.
11:07So, this is the right answer, salim steel plant.
11:11At this, stainless steel seeds by cold rolling are produced in this steel plant.
11:16Bokaru, bilay, durgapur, salim.
11:18So, this is the right answer, Salim steel plant.
11:2432, melting temperature of cast iron is 10 degree centigrade.
11:291, 900-950, 1140-12, 3,500-14, 1400-15.
11:36So, this is the right answer, D, all A, which property of the material is the most important in its
11:52rolling or forcing, ductility, malleability, hardness, or creep?
11:56So, this is the right answer, D, all B, malleability.
12:0134, number, rot iron is never shaped by hammering, pressing, casting, or forcing.
12:07So, this is the right answer, casting.
12:10Casting, casting, this is the right answer, which one contains the least percentage of carbon, pig iron, rot iron, high
12:18-speed steel, cast iron.
12:20So, this is the right answer, rot iron.
12:24Puddling process is used for the production of pig iron, mild steel, rot iron, or high alloy steel.
12:31So, this is the right answer, rot iron.
12:35Which is not a copper-based alloy, gunmetal, brass, bronze, or monel.
12:40So, this is the right answer, monel.
12:4938, number, alloy steel plant is located at R, R, R, R, R, R, R, R, R, R, R, R,
12:53R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R,
12:55R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R, R,

13:01R, R, R, R, R, R, R, R, R, R, R, R, R, R
13:06alloy sub-solder vivid metal nichrome ya monel this guy say answer have see
13:15nichrome challenge number handling cannot relieve internal stress improve
13:23resistance improve machinability refined grain structure this guy say answer
13:29hello to be improve or resistance improve resistance actual is case
13:36hardening of low-carbon steel cannot be done by cyaniding nitriding
13:42electroplating and the induction hardening to discuss science are
13:47heros to see electroplating
13:52balance number is phosphoric iron produced dash steel tough malleable ductile
13:58brittle so this guy say answer is d brittle phosphoric iron produced brittle
14:04steel 43 try it is a solid solution of carvite carvite in pearlite cementite gamma iron
14:16and alpha iron to discuss science are heros to be alpha iron
14:23so all is who each of the following process is most economical for a cv
14:28reasonable strength without developing internal stress and hardening be hardening
14:35flowed by tempering see normalizing the annealing this case answer hey see
14:42normalizing see normalizing vitalis which alloying element does not impart hardness to steel silicon copper nickel
14:55nickel aluminum this case answer hey be copper
15:02number 46 hardness bs 100 number
15:08binal hardness number of fried is about 2 50 100 yeah xo purchase discussing answer hey
15:18purchase
15:20maghanese content in carbon steel is limited to a maximum of this person one percent one point six five percent
15:29two point two percent two point two percent two point six percent discuss a answer hey one point
15:34six five percent
15:3748 notular iron does not have a poor miss nobility b height and silestrian c good fluidity d low melting
15:48point
15:5349
15:5649
15:5949
16:0049
16:01which alloying element cannot import high strength to steel at elevated temperature and nickel p silicon c
16:1549
16:1649
16:2450
16:2615. Gamma iron occur in the temperature of dash range, range of dash degree centigrade, 0 to 770, 770, 7910,
16:40910, 14, 14, 16, 49,
16:4951. Which is the most suitable process for improving mechanical properties of steel casting,
17:001. Hardening, phase annealing, C. Tempering, D. Recrystallization, allening,
17:1252. Utectoid still has a structure of perlite, martensite, sorvite, none of this.
17:2153. तो दोस्तों आज का वीडियो में इतना है, में नेक्स्ट वीडियो में, तब तक के लिए जाई हिंद,
17:33best of luck.
