Steyn is 29. He possesses a fine action, piles of pace and a hawk-like eye for the chance to turn the screws on batsmen.
"I am fortunate I've been blessed with a smooth action, but there's still a lot of work goes into it," he said. "I guess I pick and choose the times I need to force speed, to force extended spells."
He is chuffed to have made the 300 mark but was quick to point out: "I've got another test to play in Port Elizabeth, a lot more wickets to take. There's a few more years in these legs and arms."
He is matter-of-fact on his success rate since his debut in Durban in 2004 against England.
"I play a lot of games, bowl a lot of overs for South Africa and I'm always under the impression that if you do that you're going to get wickets," he said.
And Steyn, who admits occasional grumpiness is no bad thing in helping wind him up to strive for success, made no bones about his pride in the current South African team.
"This is an incredible team to be part of right now. Apart from my own game I'm just happy I am among some serious cricketers in the dressing room."
